SaveCurrentFSMState Crash
Assigned, NormalPublic
Actions

Description

Hello development team.
After update 1.27 my server crashes every day with the error SaveCurrentFSMState. The error path points to VANILLA functions and VANILLA variables. From the crash log that the server provides me I can't understand the root of the problem ABSOLUTELY.

I ask for information on this problem and fix it in a hotfix. I know AT LEAST 10 servers that are experiencing the same errors.

We really need help from the development team. Our servers and our players are suffering a lot.

I am attaching my server logs during the crashes to this report. I tried to collect all the logs.

Its non stop on our Deer Isle server and ive tried so many things with no luck. This wasnt happening before 1.27 and we havent changed anything that should cause this.

gamerz971 added a comment.Mar 25 2025, 12:11 AM

What more info is needed so this can be looked at and addressed?

Myrtan added a comment.EditedMar 25 2025, 2:17 PM

We keep getting this issue. Server crashes 1-2 times per day. Removing Magnum guns from the map doesn't help.
We're looking for the reason of the crashes, but everything seems too* complex to investigate. Do you have any additional info given in .dump files?
Thank you.

No additional information I could provide.
We are still investigating the issue.

I have the same issue.
All of the crashes have the same stack trace to the "SaveCurrentFSMState" function.

hello bohemia, we also have the same issue here, same crash, we changed nothing on our end, seemed to start after your last hotfix. lets get this fixed ASAP please. downbadservers

Gooon added a comment.EditedMar 27 2025, 4:22 PM

@Geez What else can we do to help you investigate this? Like he said this only started happening some time after 1.27 and that hotfix without us changing anything to our weapon mods. It is causing our servers much pain dealing with the multiple crashes we get daily

What has changed here from last update that would now cause us to crash if we havent changed anything related to weapons?

This is the area in the code that our crash is referring to line 564.
It seems to be all from between lines 551-575 inside of DAYZ/scripts_v1.24.157551/scripts/world/entities/firearms/weapon_base.c

we found a way to stop the crashing. we have removed all the revolvers (No matter If modded ones or the Vanilla one). Since that we dont have issues anymore. Try it maybe it will help you too. BUT we still have other fsm errors that are not related to the
revolvers, those dont crash the server.

This did nothing. I also tried spawning them all loaded and unloaded, did a bunch of testing with them, nothing.

Still continues..............

At the moment we do not require any further information.
We are looking into the issue and possible fix will be deployed once implemented and properly tested. I however cannot provide any estimates as to when this could be as this is a more complex issue. Sorry for any inconveniences and thank you for understanding.

@Geez What are we supposed to tell our clients when the server has been crashing every half hour for close to 2 weeks, and the latest hotfix is for “farming”?. What progress have you made with this issue considering it is affecting MANY large servers?

I am also continuing to have these crash logs which in turns causes the server to crash. @Geez this has been an ongoing issue for almost a month. The current state of DayZ community servers have made it almost impossible to keep servers open. Every update that is done breaks so many different things players leave. From the time of your last update you have lost 4.28% of your player base. At what point will you realize you are causing more harm with every update that is pushed? Without modded communities DayZ would have a fraction of its current player count.

We join the common problem! We are waiting for a prompt decision from the developers

This is primarily not a DayZ core issue, but an issue with mods on the server, I have found the core issues and fixed them on our servers.

maybe you can tell me what you did? After all, the developers, unfortunately, can't tell me anything, what exactly did you do to fix this problem?

Vadya added a comment.Wed, Apr 9, 12:10 AM

because here most of the servers are quite popular with strong technical skills can't fix this problem, and you found it, I hope that you will share the solution

Myrtan added a comment.Wed, Apr 9, 2:47 AM

@DozingChopper , could you tell the solution? We've tried everything to fix the problem, but nothing helped. I think it would be nice for community to get this problem solved. Thank you.

TWINKLE.Play added a comment.Thu, Apr 10, 12:09 PM

Is there any news, gentlemen?

Vadya added a comment.Thu, Apr 10, 8:51 PM

Hello, sorry for tagging, but the problem remains, the leak of players is happening further and further, I think it is unlikely that the person above found a way to solve the problem, because knowing that the problem is quite global, any person would share a solution to the problem to fix this error 'SaveCurrentFSMState'. My friend said that in his discord channel people complain about server crashes, I think he still has the same problem, I ask you to speed up the process of solving the problem, because we are losing the audience that we have been accumulating for so long due to the fact that the server does not work stably, and it consistently crashes 2-3 times a day. Please treat this with understanding, because we have been accumulating this audience for many years. @Geez

We are experiencing the same problem here, with a very large server.

My group was playing alteria flying heli and it made the whole server log out 4 times we confirmed for sure it was us crashing the server by redoing the same actions again and again (2 times the server actually crasshed and reset itself) I have the logs if somone wants too tell me how too post them.

killakisa added a comment.Mon, Apr 14, 12:47 PM

We’re experiencing the same random server crashes caused by the SaveCurrentFSMState function. The crashes occur unpredictably—sometimes multiple times a day, other times the server runs for several days without issues. We're hoping for a prompt response and fix from the developers.

Is there any update on this? This same issue on our server. Have been following this post but not seeing much input from Bohemia on this one.

Doesn't matter if it's at 10pop or at 80pop. Crashing 4-5 times a day with this SaveCurrentFSMState Access Violation Crash

Are we going to see this crash fixed before 1.28 release?

We are. Been having at least 1-2 of these crashes daily, sometimes more, and it’s really really starting to hurt. We’re still growing and it’s really not helping. Doesn’t matter if we’ve got 5 on or 40… just random weaponfsm.c crashes.

Totally. Also we've just crashed again for the same reason.

DozingChopper added a comment.Wed, Apr 16, 2:47 PM

I haven't checked this in a few days. Although yes the check itself is causing the crashing, its primarily because some weapon on your server is causing the crashing. It is checking continuously to see if the state of your weapon is correct and attempts to correct itself, if it can't it, causes the crash. Finding the fix for everyone is like finding a needle in a haystack. But for us, we improve crashing ten-fold by going through every weapon, attachment and checking to see if it is set up correctly. After finding minor issues, it improved. Although we are still getting a crash due to a final weapon we are working out, we can report that it is self fixable. My recommendation is your Units / Weapon Config & setups are all 100% correct. I will be more readily available come Sunday to look into fixing more unique instances that people may be struggling with.

DozingChopper added a comment.Wed, Apr 16, 2:48 PM

I do recommend DayZ has more of a look into the check to see if it can just be avoided completely but, chances are it is just needed to operate.

ad.HD added a comment.Sun, Apr 20, 7:24 PM

Well I really hope they do. We’ve gotten rid of like 90% of the crashes on our server by taking magazines out of weapons that spawn inside of modded crate loot, like keycards, care packages etc… but still get one every couple days for a ground weapon. It’s really annoying and I’m not at all confident that the DayZ team is going to do anything about it.

ad.HD added a comment.Mon, Apr 21, 1:02 AM

Is anyone here using SNAFU weapons on their server and still getting these FSM crashes? We used SNAFU last wipe on 1.27 and never got them, but now that we’re using A6 weapons we get them all the time. I just want to see if anyone is using SNAFU and getting these crashes before I consider going back to those weapons and getting rid of A6.

ForePlayDZ added a comment.Mon, Apr 21, 1:11 AM

I am using A6 and I recognize a few others in here that use A6 as well. I would be interested to see how many in here are using A6 Weapon and A6 Gunplay.

You can't check it because it's random.

My thoughts exactly. Not to mention I don’t have an experimental server set up to test on and I definitely don’t have players to test on it even if I did. It’s hard to just up and test this issue on experimental. Was just wondering if everyone else had the same thoughts.

I guess we just keep our fingers crossed that it’s actually fixed?

Hi Geez, we're trying on the experimental branch.

nachoooo added a subscriber: nachoooo.Fri, Apr 25, 6:54 PM

I've added a NULL Pointer check to the vanilla code to prevent server crashes. More specifically I've added NULL pointer checks on the variables ctx, state, and m_fsm in the modules weapon_base.c and weaponfsm.c. I've published this as a workshop item WeaponFSM Fix . Keep in mind this hardcodes these two modules with 1.27 code so it may break when 1.28 is released. Please remember to remove this mod when 1.28 is released.

heh, most players don't know how to run mods that are ON the workshop 🤣 Trying to teach them how on exp it'll be pushed live by time players join.

The fatal crashes or just still showing up in the logs?

nachoooo added a comment.Tue, Apr 29, 6:48 AM

I found that in addition to ctx being NULL, the WeaponDebugger and current_state_id can also cause crashing. I've added error checks for those and also redid the overrides from prefix to modded overrides which should prevent any crashing. I'm uploading the new version now. WeaponFSM Fix

Just had my first error/crash since installing your mod. One in two days is still one too many, but I’ll take what I can get.

nachoooo added a comment.Thu, May 1, 8:40 PM

Thats a bummer, I personally haven't had any crashes. Obviously its not a permanent fix but at least it will stop crashes 4-5 times a day. The main issue is the lack of sanity checks in the DayZ code and the short-circuit coding. As of this last update, Enfusion engine doesn't appear to properly handle && operator logic.

nachoooo added a comment.Thu, May 1, 9:04 PM

I'm going to make a couple tweaks to the current_state_id and see if that helps, most likely I'll upload later tonight when pop dies down
