java.lang.OutOfMemoryError: PermGen space

This error is hitting many people. The canned response is "-XX:MaxPermSize=256M" but that does not do anything for many of us though. This does not happen on 1.6 ever for us - only on 1.7+. Clearly, when its out of the blue it is a bukkit issue.

BUT not everyone has it, in fact very few. So there has to be a common thread between all of us who do have this issue but so far no one has found out and we must keep looking.

 

"-XX:MaxPermSize=256M"
how does it work?

 

KleinesGumi What is your startup script?

 

The increase in PermGen usage is because the server uses netty now. If you have a lot of plugins (or large plugins) you need more PermGen space.

 

java -Xmx7048M -Xms7048M -jar craftbukkit.jar nogui
were have dont much plugins....
before 1.7.2 we dont have ever some problems and now !

the server on my computer never crash!
