Looking to Server Test / Whizzkid my custom FTB Pack (140+ Mods)

[Revamp1984]

Hey Guys,

Ive put together a modpack, and I tried to iron out all the kinks, running it on a server with MCPC+.
but for some reason the server seems to kill itself at some point every time (no crash log)
Ive tried to host it on a different server where it gets more RAM, as without a error log I figured that would be the reason.
So now running it on 18gb server, but the server seems to not be able to keep up, and/or at some point kills itself.

Im wondering if there are any whizzkids out there that can take a look at my files and see if there is any optimizing that can be done and/or can provide me with some detail about how much RAM its actually going to take (at a base level) to run this pack as a server.

Any thought / idea's?

Update:

After completely redoing my server, ive come across a WARNING in the ForgeModLoader text file

What to do? :S

If needed, ive got a directory on DB that hold all my server files.

My guess is that it's a permgen space error. Did you add -XX:MaxPermSize=128M to your JVM arguments?

 

[Revamp1984]

Yup I checked those arguments, they all seem alright.
Ive gotten a bit further, had to ditch MCPC+ and just go for straight up Forge, it seems to be mostly stable now.
