SaveCurrentFSMState Crash
Need More Info, NormalPublic

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.

I have the same issue.
My server doesn't have any modified weapon at all, but it crashes anyway.
All of the crashes have the same stack trace to the "SaveCurrentFSMState" function.

Hello ArtemDozhd.
This issue does not seem to occur on official servers nor in our testing environment. Therefore the issue must be somewhere in your server modifications. Can you please upload your server storage so we could possibly check?

What do you mean by storage?
Storage_1 foldier?

Do you have any clues on the problem? For instance, I don't have any mods for weapons, except of retextures, but I also have the same crashes. Are there any ways to define the reasons of the crashes?

This is storage_1 from backups when there were crashes from two servers. If you need more information, I can provide it

@Geez Hello. Do you have enough information that more and more new players provide?

Geez added a comment.Tue, Mar 18, 2:26 PM

Unfortunately so far we are unsuccessful in replicating the issue

AppleCartUpsetter added a comment.EditedTue, Mar 18, 3:49 PM

@Geez Can you at least give us the information present in the dump files? What are the values of variables in the stack at the time? What are the classnames of the objects failing FSM state reconciliation? Which objects have been dereferenced? If this is, as you believe, an issue with modded content then we need more information to work around it.

ArtemDozhd added a comment.Wed, Mar 19, 12:23 PM

@Geez
Sooner or later, everyone will have such a crash. This crash happens on all servers. Somewhere more often, somewhere less often. Tell us what information we need to provide so that you indicate what exactly affects the crash? Stack trace shows vanilla functions. I tried to completely limit it, it did not help me

oldmann1991 added a comment.EditedWed, Mar 19, 2:12 PM

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.

Good day, every day after patch 1.27 the server crashes with the same error as others who came to you with the same problem.

Nothing we tried helps, I ask you to understand the situation, because it is impossible to tolerate.

I have dropped the crash log below, please help me find a solution.

Everything was translated through Google translator.
