java.lang.OutOfMemoryError: Out of swap space

[fangj]

My jboss version is 3.2.5, OS is linux, total memory is 4G, swap space is 4G. The java version is 1.4.2_03.
The java option is: -server -Xms2000m -Xmx2000m -XX:MaxPermSize=128M -XX:MaxPermSize=128M -XX:NewSize=512m -XX:MaxNewSize=512m -Xss512k -Djava.awt.headless=true

The maximum thread is set to 280.

After random time( Maybe 12 hours or serveral days) , the following error occurs:
Exception in thread "CompilerThread1" java.lang.OutOfMemoryError: requested 1508992 bytes for Chunk::new. Out of swap space?

Would you please tell me how to fix this problem?

Thank you very much!

Fangj,

Did you ever get this resolved? I have a similar error with 1.4.2_08

Thanks,
Mike

I set the option as the following, and things seems to be right
But I don't know why

JAVA_OPTS="-server -Xms2000m -Xmx2000m -XX:MaxPermSize=128M -XX:MaxPermSize=128M -XX:NewSize=512m -XX:MaxNewSize=512m -Xss400k -Djava.awt.headless=true "
