We had a similiar issue. Let me preface by saying I have not read this entire thread so if the info I give is redundant.. sorry.
Anyways, we had a similiar issue. Code that worked fine under CFMX 7 would cause Jrun & cfmx 8 to suck down memory until it crashed. We narrowed it down to a piece of code that read in a large xml documented, parsed it, and then displayed it on the screen. Hit it once after the server would start and it would take 200 megs, hit it quickly a couple times and it would jump to 800 meg(max jvm memsize was 1.2g), do it a couple more times and the instance would crash. I was able to catch the ear of an Adobe support engineer and we have solved my problem. First, I upgraded to the lastest JVM 1.6_06 also, scaled down the memory quite a lot. Here is my jvm.config: java.home=d:/jdk1.6.0_06 java.args=-server -Xmx512m -Xms256m -XX:MaxPermSize=178m -Dsun.io.useCanonCaches=false -DJINTEGRA_NATIVE_MODE -DJINTEGRA_PREFETCH_ENUMS -XX:+UseParallelGC This has totally solved my problem our servers have been running great ever since. Plus 1.6 is much faster. Hope this helps. - Alex ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;192386516;25150098;k Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:307374 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
