Symptoms

Managed Server started with 12gig runs out of memory

You have just experienced an issue where your live production weblogic managed server went very close to running out of memory....only .3 gig left of original 12gig it started with. You bounced the managed server to reclaim all the memory and it is back up running again with 12gig...and showing 90% heap free. Thus the primary question is why does this heap size grow? You have a pretty static average user load of no more than 50 users and during their performance testing, even with 150 users, you believe you never saw the heap usage rise much above 50% (6 gig).
