Hey all, Hoping one of you guys who are CF folks but also know something on JVM and heap memory management (and how CF affects heap usage) can shed some light on my situation.
Basically my server (CF9 on Linux) has been having heap memory issues from the get-go. And this is after moving everything from a like-configured server running Railo, where it was worse. From what I can tell, a server's old-gen heap space should be emptying out significantly with every GC run - mine, not so much. From the time the service is restarted the old-gen area slowly creeps upwards in usage, and the GC runs only help with what I can best describe as the usage since the last GC. I'm not a Java/JVM guy by any means, but best I can tell this is aberrant behavior - using the FusionReactor demo on their own site, pointing at a server they have running with tasks kicking around to show activity for the demo, their old-gen area climbs steadly up up up to the max, and then plummets to a small fraction of the total area. Completely different than what I see with my server. I've got FusionReactor running and have been trying to puzzle out what the cause of this behavior is for a while now. I've lately been doing some furious recoding of portions of my codebase, to try and improve performance and more specifically, attempt to head off any memory leaky/intensive code usage. I've made some small progress, but nothing substantial - now my server just takes longer to get to an unusable point due to heap levels than it did before, the old-gen heap levels take longer to inch their way up to the max allocation and stay there. Is this a problem that one's CF codebase can significantly contribute to, or cause outright? Or more of a JVM config issue? Or both? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| 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:353494 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
