coldfusion server monitor jvm snapshots

Question

one my server instances has started to go haywire in a multi-instance setup running adobe coldfusion 8.1 enterprise. the built in cf server monitor is throwing these alert snapshots constantly, however, this same box is running Fusion Reactor {http://www.fusion-reactor.com/fr/} and I can not figure out where they are coming from. anyone have any pointers or a good tool to decode these files?

Answer 1

I suspect you have an snapshot/alert set to collect a snapshot file when your JVM allocates more than 1000 megabytes of memory. This is probably not a great idea since under normal circumstances your Jvm might indeed allocate that much and recover with a GC. I would look at your alert/snapshot settings and adjust them.
