My server repeatedly crashes within about 30 minutes to an hour from what seems to be an outofmemory error.

That's the crash report, and this is my serverstart.sh file

java -Xms16M -Xmx2048M -XX:permSize=256m -XX:MaxPermSize=1024m -jar ftbserver.jar
Click to expand...

Any help would be appreciated I've been trying to fix it myself,but I haven't been able to.

Well it's enabled, but I don't know that anyone is using it.
Edit:
Checked around, and no one has logistic pipes anywhere.

I've seen that forum post, and used every code for the serverstart.sh script. Nothing seems to work. I searched for hours on solutions and tried pretty much all of them before I made a post.

Try setting it to -XX;PermSize=128M -XX:MaxPermSize=256M. Having a whole gigabyte of Perm space is unnecessary, especially when you only have 2GB of RAM.

Code: 
java -Xmx2G -Xms2G -XX:PermSize=256M -XX:MaxPermSize=512M -jar server.jar nogui
That's the server file atm I've got 2.5 gigs of ram in all

Again, try setting it to:
Code: 
java -Xms2G -Xmx2G -XX:PermSize=128M -XX:MaxPermSize=256M -jar server.jar nogui

and post the results. Even 512MB is a bit much for what I assume is a smaller server (based off of ram). I have a pretty large server and only set it to 256MB.

Alright I've set it to that I'll tell you if it crashes and try to grab the errors from console before it restarts itself. It hasn't been generating a crash log lately.

You should be able to fetch it from the server.log file instead of copying from the console, which is in the same folder as your server's .jar.

Any idea how much of the RAM is being used at the time? It may just be that 2GB isn't enough.

Well, Perm gen space still does come from the RAM. I'm not too sure what else to do, though. Sorry :(

Before I say anything. Do you seriously have a 2.5 gigs of ram TOTAL or 2.5 gigs of ram AVAILABLE? There is a big difference.

Edit: also are you renting a server or is this your server.
