I'm also receiving the same exact crash, happens intermittently and cant figure out why.

Nessiroj · Jan 23, 2013

Not sure if thats the cause but how much ram do you have in your server? seems 7GB and you send a startup flag of almost 8GB

Code:

Memory: 636463512 bytes (606 MB) / 1164247040 bytes (1110 MB) up to 7135952896 bytes (6805 MB)
    JVM Flags: 1 total; -Xmx7656M

and can you paste the serverlog to pastebin?

Rlvassallo · Jan 23, 2013

sure will do.

edit: here it is http://pastebin.com/8VgKg0GC

Nessiroj · Jan 23, 2013

thats the crash report not the serverlog

and how much RAM is in the server?

Rlvassallo · Jan 23, 2013

2gigs ram, yea i realized after i just reread previous request

server log: http://pastebin.com/PcgDqTHa

Nessiroj · Jan 23, 2013

Code:

2013-01-23 23:15:23 [SEVERE] Encountered an unexpected exception OutOfMemoryError
java.lang.OutOfMemoryError: GC overhead limit exceeded

that's the cause of the crash

If the server has 2GB of RAM, why are you starting the server with the 8GB flag then?

Code:

JVM Flags: 1 total; -Xmx7656M

What OS is the server running?

and i'm not running it at 8 gigs, that's the OP's post

Nessiroj · Jan 24, 2013

sorry was abit confused lol.....
your server is using max 350M? thats aint enough for FTB 1 GB minimum recommended
If you have 2GB with an FTB server and Linux (not sure if there is anything else running on the server) i whould say change the -xmx1000 or -xmx1500M

Rlvassallo · Jan 24, 2013

ok, thanks when i saw that i was thrown off as well, how would i go about getting that done, which file?

Nessiroj · Jan 24, 2013

Not entirely sure about nix-based systems for windows it's in the start server.bat file. I presume your starting the start server.sh file? then you have to edit that line
where you see the -xmx350M into -xmx1500M
