Subject PermGen space during operation
Date Thu, 19 Mar 2009 01:20:03 GMT
I got a bunch of these out of memory exceptions (ODE 1.2, tomcat, Linux,
Hiberate, Oracle). The surprising part is that these occurred only after
ther server was running happily for a while.As far as I know, PermGen
space is only used for the actual class definitions, and I'd expect that
after some stabilization time after startup (and I'm not deploying
anything new into the engine), then PermGen usage should be stable.

Are there dynamic classes being generated?
