One again my memory usage was steady at 20%, something happened and now its up and down from 15% to 90% and back down within minutes. Here is a screen shot of the memory graph in seeFusion. GC seems to be doing its job, but this does not seem normal or does it!?
http://screencast.com/t/6SkU3bF9Gsx So I did a heapdump and analyzed it in MAT for eclipse: When I took the dump memory on the server was reported at 90% by seefusion. The JVM has 1 gig allocated to it. The dump doesn't show near that much memory in use, so maybe a GC ran right before I took the dump, I'm not sure. Does anyone see anything that stands out in these reports? Should there be that many jdbc.base.preparedStatement items? http://screencast.com/t/Th4ZiLZw http://screencast.com/t/IdGqa6Uh On another note, its pretty cool that you can see whats stored in the application scope and its memory usage. This screenshot shows the structs/arrays/strings that are application scoped: http://screencast.com/t/XZyRofWTJNN Brook -----Original Message----- From: Mack [mailto:[email protected]] Sent: December-06-10 4:07 AM To: cf-talk Subject: Re: Memory Usage Question > I wish I could see WHAT was taking up the ram, i.e a specific array, cfc > instances, etc etc.... It can be done but it's not easy. Basically you need to do a heap dump of the CF process (you can do that without shutting down the server) and then analyze the heap dump using MAT for Eclipse. MAT can tell you what are the objects on the heap, etc. -- Mack ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:339908 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
