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.
Best regards,
