Problem Direwolf20

[Darkarma]

Been messing with Direwolf for nearly the past twenty hours and partially solved my issue for my small home server I share with a few friends.

Essence:
When I run the server through the FTBServer.jar it will eventually crash before anyone has a chance to log in. This is before I even install Gregtech or Treecapitator.
Circumstance:
Windows 8
32gb of ram, 8 of which are dedicated to the server.
Each attempt I've done has been with a freshly unzipped copy of the newest direwolf server pack.
I am a bit new to hosting a server just as a note.

And that's it. This happens every time, it either complains about about permgen (which I increased its capacity afterwards) or about biome o plenty.

How I fixed it:
I stopped using the ftbserver jar program and just ran with the start.bat After that the server works fine I can log in and everything. Works fine even with the additional mods mentioned above.

My question:
How do I fix the blasted thing so I can use the server jar...? Or does anyone have some recommendations on what to replace it with? Personally I'm a fan of having things with lots of buttons and fields and the like... I can deal with using the cmd if I have to but its not ideal. I'll take it if it means a more stable server.

Help?

Side Note: Apparently treecapitator isn't working but its not bringing down the server either.... dunno

If you edit the start.bat and remove "nogui" from the end, I think it might still show the GUI with the buttons and fields you like so much! I think the problem is that by double clicking the .jar you are not specifying any Java command line arguments. With FTB Servers it is imperative to specify at least the

-Xmx -Xms and -XX:permSize

Java arguments.

Hope this helps and isn't something you already knew!
