There was a 100-150MB difference between the Memory Usage reported in CF Admin (which I'm assuming is taping directly into JVM?). Thanks for the tip with the Task Manager. I don't seem to have a PID for VM Size?

Mem Usage is the amount of physical ram currently in use by a process, but VM Size is, well, different. If you have less physical ram on a machine then you may see less Mem Usage but more VM Size (and probably lots of page faults as memory is swapped in and out, seen in Task Manager as "PF Delta"). I always show both Mem Usage and VM Size in Task Manager to get a better picture of actual memory requirements.

The numbers I've been quoting are from Jrun just after boot (idle, no applications loaded) or after only running CFAdmin. Maybe Jrun needs some time to configure itself and requires extra memory when first installed? Maybe the same can be said for when the machine boots? I don't know, I'm merely asking. The new box is now running at 165MB. The settings are default (as verified earlier). I'm content with 165MB. -----Original Message----- From: Mark Kruger [mailto:[EMAIL PROTECTED] Sent: Friday, May 16, 2008 5:31 PM To: CF-Talk Subject: RE: **UPDATE** JRn 600MB+ shortly after boot up What makes you think that is not right? If your Max is set to 512 and you load something as an application, the JVM will determine when to recover memory based on it's own timetable and settings. 427 megs could indeed be appropriate depending on the settings. There are some code snippets on this post that you can use to fiddle with the JVM gc operations - although I would not use them in production. http://www.coldfusionmuse.com/index.cfm/2008/2/12/leaky.heap.jvm If forcing a "stop the world" gc brings your memory back down you are probably worried about it for nothing... Since the JVM will eventually run a full gc on it's own. -----Original Message----- From: Jason Durham [mailto:[EMAIL PROTECTED] Sent: Friday, May 16, 2008 2:03 PM To: CF-Talk Subject: RE: **UPDATE** JRn 600MB+ shortly after boot up I rebuilt my machine again. This time... no Windows updates, no antivirus, nothing... I immediately downloaded the latest installer from Adobe and installed it (Server config with all IIS websites). JRun is running at 427MB.
