Following up. After going round-and-round with the hardware guys, they finally called Microsoft who had them get a crash dump. MS's analysis says that the culprit is JRUN_IIS6_WILDCARD.DLL.

Okay, I can see instructions in the Adobe Knowledgebase on how to do that, but I'm not finding anything which talks about this file bringing down IIS. Am I missing it? Also, how can this file be implicated when the most reliable scheduled task in bringing down the Application Pools was the one that ran every 61 seconds and called a vanilla HTML file? -----Original Message----- Got a scenario I'm currently investigating. Our test and production machines are crapping out on a daily basis. It appears that something ColdFusion is doing is bringing down the IIS application pool. Oddly, the identically-configured development server is unaffected. What would cause that to happen? A runaway memory leak? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:251520 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
