Client purge crashes CF

We're running ColdFusion 9.01 Enterprise, Windows Server 2008 R2 (OS version 6.1).  The good news is that the server autostarts very quickly after the crash, such that it is hardly noticable.

Beginning a few weeks ago, we noticed this behavior and we're not able to associate it with any change.  What we've found is that every 1 hour and 7 minutes when the client purge is executed, we get a module fault in CFRegistry.dll.  We've tried changing the purge interval and also have tried changing the storage from registry to MS SQL.  No matter, the crash still occurs.

Is this a known issue, or is it known under what conditions such a thing occurs?  Dump is below from our event log.

Thanks,

Chuck Wyatt
