Hi Phil, There have been several APARs related to leaking memory for system state backup (you can look these up on the link in my sig), IC55515, IC55516, IC6962 (this last one most likely not your case). These should be fixed at the 6.2.2 level. If you are seeing the 20 - 50 MB leak at that level, then please open a new PMR, as this needs to be investigated; if you get the "use the CAD" or "stop/restart the service" response, send me an email to let me know the PMR number.
