Did you try putting it on a more stable desk? *grin* Eric -- From: Glyn Jackson glyn.jack...@newebia.co.uk Sent: Monday, October 12, 2009 2:25 PM To: cf-talk cf-talk@houseoffusion.com Subject: ColdFusion Server keeps falling down!

Re: ColdFusion Server keeps falling down!
I then try and restart the service and it errors stating CF cannot be stopped That's pretty normal for an overloaded server.. takes a while to shut down. Since you're running fusion reactor... tell us how busy the server is. Look at the request activity graph.. what's the average? Maybe the old server had more than 512MB allocated. A quick fix would probably be to allocate more memory to the instance, assuming your virtual server has more memory available. Long term though, you have to figure out what's using the memory, which is more difficult. Look at the memory usage graph... does it go up and down A LOT? I once had a problem where the server was doing massive amounts of garbage collection every 30 seconds or so.. we also had a significant CPU issue because we had 1500 subdirectories each containing 120 files that were exactly the same (not my architecture!)... so template caching was non-existent and CF had to compile every page on the fly. Perhaps you're storing a LOT of stuff in a shared memory scope, like the application, server, or session scopes. Rick ~| Want to reach the ColdFusion community with something they want?

RE: ColdFusion Server keeps falling down!
I'd check the JVM settings for memory allocation and compare them against your old server if you can. Paul ~| Want to reach the ColdFusion community with something they want?

RE: ColdFusion Server keeps falling down!
There's all sorts of memory settings and I recently had out of memory issues that were related to the Eden space which were solved by increasing the value of -Xmn to 128m. There's a great article on tuning and memory usage here: http://www.adobe.com/devnet/coldfusion/articles/coldfusion_performance_01.ht ml Paul -Original Message- From: Glyn Jackson [mailto:glyn.jack...@newebia.co.uk] Sent: Monday, October 12, 2009 8:47 PM To: cf-talk Subject: Re: ColdFusion Server keeps falling down!
