Problem FTB Unleashed Crash

[FaceMcShooty]

So, I've been running a FTB Unleashed server for about a week. Before this, I ran an FTB Ultimate server with 0 issues. But, the Unleashed server is giving me a lot of issues. I am hosting the server from my personal desktop, running Java 7 64 bit.
The initial .bat file code i was using will be posted below, along with the crash report. If anyone can help me figure this out I'd be very grateful.
PS>The server is able to run for 20-30 mins before crashing.
Will upload a screenshot of the command prompt as soon as the server crashes again.

Was there a crash report file generated?
If there isn't one and you have no clue what is happening, delete every single file of your server, exept for the world and get a fresh set of server files, I wouldn't know what else to do, but I'm not much of an expert at this

I can not find a crash report anywhere. The only thing is the server crash report I posted above. Named server1.txt

Well if I can read that screen-shot correctly your running out of physical memory (not perm gen at least from the blurry image). So in your startup script need to asign more to it. Currently you have 3GB assigned to it, which I would normally say is enough for any personal ran server. Which leaves me to believe something is wrong with your garbage collector, so update java.

Had the current version of Java installed. Re-installed it and now running the server. Will update when it crashes again...I know its going to. Just a feeling.

You can also try something that was posted on mystcraft's wiki: http://binarymage.com/wiki/doku.php?id=setup:memory then go down to server part.
