I have finally set up a local server, which works fine. However, occasionally it sort of freezes for up to 15 minutes.
Eventually the log shows something like "10 ticks lagged for 20 ticks adding 197057ms".

The server itself does not freeze entirely, it's just the entire world interaction/ticks, which do not get processed. If i try to log in during this time, it will show i tried to connect. Commands on the server also don't get processed.

This is the command to start it up. "java -Xmn2G -Xss4M -Xms3G -Xmx3G -XX:permSize=256M -XX:parallelGCThreads=8 -Djava.net.preferIPv4Stack=true -jar FTBServer-1.6.4-965.jar nogui"

Java is Java HotSpot(TM) 64-Bit Server VM, version 1.7.0_51, running on Windows 7:amd64:6.1

Any ideas on how i may resolve this? I'm hoping it's just some of the command-line parameters.
