When reporting a crash you need to upload a dxdiag report and the files from
C:/Users/<Name>/AppData/Local/DayZ/

Pack the files into a .rar file - if the RAR is smaller than 5000KB, you can attach it here. If it's larger, please upload it to a file sharing website and link it here.

For future reports please refer to the "How to guide"
http://feedback.dayzgame.com/how-to-user.html

Thanks

ok if its happening again, i will upload the dxdiag and the game files

Same issue for me, exactly as described. (Also on win 7 64-Bit)
Try to connect to another Server (maybe after Message "Session Lost" and then reconnect?), then DayZ crashes Windows says "DayZ stopped working".
My clone wont disappear execpt for killing him.

don't kill the clone when you log back onto the same server ... if you kill it and then log off and back on another time you will come back as a freshie

Had the same crash again a few minutes ago, I can provide the Logfiles

This might help, I get the same random quit without warning. Just drops to the desktop and windows gives an error

I have testet something.

Disconnect from Server - Join another/same Server -> Dayz crashed

Disconnect from Server - Restart Dayz - Join Server -> No Crash

With our players, it goes like this. Can someone confirm this ?

Right got to the end of it today.

1. If you have a hard case in your kit you'll get the disconnect.
2. You'll also find most of your kit now shows as RUINED when you come back on the server, this happens more often if you've crashed regularly (like me)
3. The ruined status spreads slowly over the rest of your kit

I've dropped my hard cases and had to drop every bit of ruined kit, even my clothes, it's basically respawning but with a gun (ammo ruined)
Things I'm picking up now are staying at normal status so far and no crashes. Seems to be hard cases so far

@ bobbyboy,

it happend now severals times, I got the disconnect without having a hard case.
An I also had nothing ruined after reconnection.

@NoOneKnows

Damn, I thought I was on to something there. My crash has stopped now that I've dumped most of my stuff. I was getting the exact same problem though, random crash to desktop and the same when I try to change servers.
I hope they sort the problem soon

happened again after Server Restart. tried to connect to another Server....

Started with 0.45 update, but crashes every time i quit dayz. I can play for hours.

Ok, I fresh spawned so there's nothing on me. Tried to switch servers and crash to desktop.
Restart Dayz, I can join a server no problem and play on that server for a long time without issue. Exactly the same error from Windows above.

When I come back into game after crash some of my items are damaged or even ruined if they were previously damaged making the game kind of useless to play as you'll loose everything you own with random crashes.

I uploaded my crash-report-files (DayZ2.rar) too.
Just in case it's important: I deleted the -noLogs launch option yesterday (22.06.14) for the first time, to send you the best possible crash-report. (Normally I keep this active to guarantee best possible game-performance). So what ever this option affects and what ever you can see in my report - it might be "complete" since that date.

I have not managed to make some testing to isolate the problem yet. All I can say is there are "random" crashes while playing and "foreseeable" chrashes while changing servers or quitting the game.

The same thing happens to me every time I play dayz, it is the same as it was on the experimental branch when 0.45 was there.

The game was a lot more stable once and now it is just about unplayable for testing, only for the crash testing now. I hope it will be fix soon as this is hindering the testing process of the actual game.

Just on another note to the devs. I have played a lot of alpha early access games and dayz in my opinion is one of the best game concepts but with very poor development progress, other games have regular update to fix issues without creating more to make the game unplayable.

This Report needs more attention, due to the fact that the game crashed are still in 0.46!
This has become so annoying, every Server Change result in a game crash now.

Yes, NoOneKnows is right. Today I got the crash report files of a friend. I uploaded them to http://www.manuelnuetzinger.com/data/dayz/DayZ3.rar

same as me :( do you guys have a crash too, when i leave a server and choose the back buttom to main menu the game crashes after loading the main menu?

Files as requested by R834:
https://www.sendspace.com/file/ocx3mu

I have been reproducing the same crashes as stated.

1. Start game.
2. Connect to server and play for any amount of time.
3. Disconnect at any time or when the server restarts.

4a) Connect to the same or other server and the game will show the Please Wait black screen but then crash to the desktop with the same error messages posted in previous comments.
4b) Alternatively, press ESC while on the server list menu to return to the main menu. My character and the background partially loads, but the game then crashes to the desktop with the same error message.

5. Reload game and repeat.

If I go down the 4a path, my other problem with this is that if I connect to the same server at step 5, I create a duped character at the same location where I disconnected/crashed from initially and that character persists in the game world until the server restarts. It never disappears even though it goes through the lie down/crouching animation as if it will eventually vanish. So now I'm concerned that this duped character could be killed by bandits and I will lose my 'real' character.

I don't know if that character persists if I connect to another server as I have no friends to confirm this with. However, I can confirm that when I load the game for the 2nd time, my crashed character loads just fine, but if I connect to a new or 2nd server and modify the character a with loot and disconnect/crash to desktop and load the game for the 3rd time, my originally crashed character will load in the starting menu instead of the new modified character. That said, if I then connect to the 2nd server where I modifed my character, my modified character will load.

So now having exited the game for the 4th time, I'm wondering which character I will load on the 5th time. We'll see.

Update: When I connected for the 5th time, my very first crashed character loaded into the menu, but when I connected to the '2nd' server, my modified character was saved from before. After playing a bit more and exiting the server, I was able to get to the main menu without crashing and my modified character loaded, replacing my crashed character. I then exited out of the game for it to crash again with the same error message.

Me and my group found something:
As I wrote earlier, there are sometimes game crashes while playing.

Everytime a game crash happens to one or some players on the server, the rest of the players, staying on the server, get the error message: "Confirmation of Changes - Cannot load material file .". (See the screenshots changes1 and 2.)

We found a way to avoid these ingame game crashes: Everytime we change servers we completely close DayZ and restart it. Using this routine helps us staying ingame and getting the error message instead of a game crash.

@ Nihil Baxter,
Sadly thats what I and my crew are doing for weeks now.
Whenever the Server crashes or restarts, we restart the DayZ Standalone Client.
However, this is just a workaround and no solution, maybe gets fixed in 0.47 stable?
Hope for it,
best regards.

yesterday i played with my friend, after leaving server and not restarting dayz his game stoped working as mentioned. so after he came back in he wanted to wait at how long the double would stand there, but as we saw the restart was a hour and a half away. we decided to kill the double and loot it. after this my friend logged out joined another server and viola he was not dead. so he joined back to the original server and still wasnt dead. so it looks like the double isnt connected to the player anymore?! the dead body was visible and lootable for at least 20 minutes(until we leave, i think until server restart) not like normal dead bodys that dissappier or become unlootable in 5-10 minutes.

We made the same experience, BloodbathG. But the game crashes still have to be solved.

If you check the Pulse of the double, and its named Unknown Entity, then you can safely kill and (hopefully) Hide the Body!

just tried experimentel 0.47, looks like the bug is gone in this version.

Have not seen the bug in 0.47 stable yet.
