Hi Rich,
We haven't ever really fiddled with GC parameters, instead we leave the
whole GC settings up to the "-server" JVM.
We've never seen this error on our servers. It doesn't look like your
error message is related to the "OutOfMemoryError: PermGen space" issue
so I'm not sure "-XX:MaxPermSize" will help.
Have you tried adding more memory to the heap ("-Xmx")? And if so did it
help?
