Re: Mapping a session to an allocation of virtual memory

Use "onstat -g mem" when it happens again. It should show some very large pool. If the pool name in column 1 is a number than this is the session number (use onstat -g ses <num>). But it's possible that the memory was not allocated for a particular session. If you can send me the output I will try and tell you more.
