When running Solr we are experiencing PermGen OOM exceptions, this problem gets worse and worse the more documents are added and committed.

Stopping the java process does not seem to free the memory.

Has anyone experienced issues like this.

Kind regards,

Richard

so have to increase the memory available to the JVM, what servlet container are you using?

PermGen memory has to do with number of classes loaded, rather than
documents.

Here are a couple of pages that help explain Java PermGen issues. The bottom
line is that you can increase the PermGen space, or enable unloading of
classes, or at least trace class loading to see why the problem occurs.
