That could be related to a common classloader memory leak.  See this

Subject: [Resin-interest] class reloading / out-of-memory


hi,

i have the following out-of-memory error when changing a class file of a
web-app
and the web-app is re-inited:

---8<---
java.lang.OutOfMemoryError: PermGen space
     at java.lang.ClassLoader.defineClass1(Native Method)
     at java.lang.ClassLoader.defineClass(ClassLoader.java:620)
     at
java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124)

     at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)
---8<---

this regularly happens after the app is reloaded for the 5th or 6th
time.

the admin service works without a flaw and indicates that there should
be enough
free memory:

Total memory:   122.42Meg
Free memory:    56.45Meg

any hints where to look?

i'm using resin 3.1.1 and jdk 1.6

best regards, --- jan.
