I have a situation where I am running out of permgen space on a regular basis. I can literally what the permgen use grow until the server falls over. I have seen numerous other ticket that point toward this actually being a plugin issue, and that the only way to troubleshoot this is with a Memory Dump. I am of course able to increase the amount of PermGen, but all this does is delay the inevitable. No matter what levels I set permgen to, it eventually falls over.

I have attached a memory dump.
