Hi Stephanie,
Im a Project Manager, not a techie but we had the same problem and had to
increase the perm gen to the following: Tomcat sets it at default at 64MB.
Perm Gen Memory: 150 MB
Max Perm Gen: 256 MB
We where getting perm gen out of memory errors which is why we did this.
This stabilised the environment but we still have problems with our Heap
Memory filling up and not been garbage collected properly.
Kind Regards

We see this same behavior. I too am interested in comments from
others. We are running on a OS X Server; JVM v1.5.
