Problem FTB Unleashed Nether gen freezes/crashes server

[Razzle Storm]

Hi! I've searched for this and found no threads, so hopefully this hasn't already been addressed somewhere.

Basically, on my own server, whenever I make a portal to the nether and try to go through, the game gets stuck on the "loading world" page, and then the server freezes and eventually stops responding. I've left it for 10 minutes before to try to see if it would work through the issue, to no avail. I've restarted the server and found myself in the nether (with no nether portal spawned), but I can't go back through any portal I make without crashing the server again. I'm not sure if it is just me, as other players haven't been on to test it yet. Watching it as I produce the problem, the server memory use gets higher, and (% free) counts down until it reaches 0, then it freezes, and I have to end the program.

Some specs (let me know if you need more?):
Running on Windows 7
Using FTB 1.1.3
with no extra mods
Server specs are currently looking like this, but I can bump up the RAM if I need to:

java -Xms512M -Xmx2G -XX: permSize=128m -jar ftbserver.jar

Thanks in advance for any help you can provide! I'm sort of new to running a server, and am learning, so let me know if I need to provide more information.

Now the latest pastebin: server log snip

We do need more, but not system specs, we need logs. A console log in debug mode posted to pastebin.com and linked here should be enough.

Just realized that as you posted. Is that snippet I just edited into the first post enough? I only see the one log file, and tried to edit it to just the latest server start, instead of everything from the start of the server itself.

Also, I have tried deleting the nether folder and trying again, but to no avail.

Um. Are you using the .bat file to start the server or just using the .jar? Your not passing any arguments to java at all and running out of memory.

I was just using the .jar. I'll try with the batch file.[DOUBLEPOST=1378936597][/DOUBLEPOST]That fixed it. Thank you very much! Like I said, I'm still learning. >.<


For about 5-6 people, what should the batch file look like in terms of RAM? Would

java -Xms1024M -Xmx2G -XX:PermSize=128m -jar ftbserver.jar

be okay?
