Thanks, Peter. To answer some of your questions... No, we do not redeploy very often, but we were running into PermGen errors daily with the default setting. Curiously, it was only 1 of the 2 servers. The other is/was configured exactly the same way. The load balancer is supposed to alternate sessions between servers, but I don't know how well that is working. I am curious as to the -ms/-mx settings given the amount of memory available in our system, but I obviously don't know how this really works. I will look at the link and the presentation included within. I do not believe it is the 64-bit OS or JVM.
