Subject RE: PermGen space during operation
Date Thu, 19 Mar 2009 01:31:09 GMT
Nope... 

I assumed that reloading would be bad.. ;)

This is a server that just sits there and gets load tested.

 

I'm not sure how to check the revision - I'm using a binary
distribution.

Andi,

Are you re-deploying your projects over and over? And, does your ODE 1.X
local copy include the revision shown below? If you answered "yes" and
"no" respectively, then you should be able to resolve the issue just by
updating your local copy.

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?
