Problem Crashing all the time?!

[behedwin]

Hi

I am having big issues with my FTB Monster pack.
Some of the players on my Creeperhost.net server are crashing all the time. Some are not crashing atall. I dont know what the problem can be.

Here is a fresh crash-report
https://dl.dropboxusercontent.com/u/12344784/Ny mapp/crash-2014-06-11_16.36.06-client.txt

Anyone able to help me locate what the issue is?

That should be a serverside error.

So since i run the server on creeperhost.net

what should i tell them... So far they have not been able to help me
I have reinstalled the server several times and still it is not working.

 

[Wagon153]

Well if it's client side crashes, it has nothing to do with your host.
Do they crash in specific places? Do they have any special mods(like optifine) installed? I'd blame Greg, but Greg takes extreme care to catch all his crashes.

 

[behedwin]

No, nothing special installed on the clients. No optifine and no, no crashes in specific places.

Very frustrating and i dont know what mod could be the cause to this.

It helps to remove the player.dat file
but that resets the player and removing inventory for players every second day is very bad and not a solution.

Well I can give a little background on the error. A concurrent modification exception happens when two mods try to change the same data at the same time, such as a player.dat. Do they have anything like backpacks in their inventory? Or a specific item they have that those who don't crash don't have?

 

[behedwin]

nope. for example i crash allot and i have no backpack. I have basically only played vanilia style so far.
However i do have advance genetic on me... donno if other have that.

 

[Wagon153]

That could be the problem. Avoid using Advanced Genetics and see if that helps. Remove the mod even.

 

[behedwin]

Uninstalled the mod on server and client
Reinstalled my whole client

Could login, played... loged out and went to work.
Come home from work and try to login, crash again.

Now i can not login again.
Why is this happening.

 

[behedwin]

Made an support question for this.

i still need badly help to solve this. I cant figure out why this is happening.

seems like it could be a problem with statuseffectHUD, try removing it.
