Hi All, We are having some terrible server issues at the moment, and now we need some outside ideas, as we have run out!
The symptoms of which are as follows. About every 3/4 hours jrun (CF7) locks up and hangs at 25%, SQLServer 2005 stops doing anything. The server has plenty of RAM (3.5Gb), and is usually sitting at about 50% usage. The waiting requests number goes up and up, and CF doesn't seem to time out the requests running fast enough. We have this set up to timeout after 30 seconds. Server is Windows 2003 Server, Xeon 3.00GHz. Performance monitor suggests that CF easily copes with the load, only a few timeouts, but always 2-4 simultaneous requests runnnig. Current Java Args are: Java VM Arguments: -DJINTEGRA_NATIVE_MODE -DJINTEGRA_PREFETCH_ENUMS -XX:+UseParallelGC -Xms512m -Xmx512m - Dsun.io.useCanonCaches=false -XX:MaxPermSize=128m In CF Admin we have 8 simultaneous requests, caching 5000 templates, Save Class files ON. We have been using VisualGC to see what the JVM is doing with its memory. We have since upped the Xms and Xmx to 850 and have thus far been up for 2h 15m. SQL is running at a limited 1Gb memory. My questions are this: In VisualGC we are seeing that the OldGeneration goes up and up, and doesn't seem to fall very much - is that normal? VisualGC shows that we have 20800 class files loaded, but only 9500 are actually unloaded. Again - is this normal? We have done lots of the usual things, defrag disks, optimise queries and tweak code, and made some progress, but its still happening. What else can we look for / do to try and resolve this? Thanks in advance, I hope you can save my hair before I pull it all out! -- Duncan I Loxton [EMAIL PROTECTED] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:298968 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
