Mark Thanks for the reply.
I've gone through a few things and shifted all our direct use of log4j to commons-logging (this may not be a good thing, but consistency was the point) and then put commons-logging and log4j into tomcats common/lib directory... (recommendation from a colleague) Re-running this with a profiler has shown that things appear to be cleaning up better and the heap space has a much more significant garbage collection afterwards. Problem is that permgen space still appears to ONLY build up... Do you know of any ways to track down what might be 'stuck' here or a starting point I could use? If you have any info on the logging issue it would be helpful but from my Google searches everyone seems to have a differing (if only slightly) view on this.

Your understanding is correct.
