Hi I'm trying to start up a ftb server. I encountered a permgen error while trying to launch the monster mod pack on ftb.
steps I've taken:
redownloading the mod pack
trying to startup the server multiple times
letting the server try to startup overnight
modifying the startup files with this configuration "java -Xms4096m -Xmx4096m -XX:PermSize=512m -XX:MaxPermSize=1024m -jar FTBServer-1.6.4-953.jar nogui
pause"

system specs
eight core processor 4.0 ghz
8 gigs of ram
64 bit os
64 bit java

The errors in the forge log files start here:

any help is appreciated.

I fixed it by running it through CMD rather than the jar
