Exchange Information Store Instance

One of my Exchange Mailbox cluster resources keeps failing causing other resources to fail.  The Exchange Information Store Instance keeps failing and taking other resources offline every 5 minutes.  I can go into cluster administrator and bring the resource back on line with no problems.  There is nothing in the event log to point to what the problem could be.

You could remove dependancies from cluster services to stop the one service from taking everything else down.... but it would better to find the cause....

if there is nothing in the event log - you might want to turn on cluster diagnostics logging - but if the cluster services are being re-started, there would HAVE to be something in one of the logs.

After working with Microsoft for a number of hours, we found that one of the Information Stores had a problem.  I dismounted the the rouge database and that stopped the Information Store Instance resouse from failing.  We ran isinted utility on the database (isinteg.exe -s (Exchange Server name) -fix -test alltests and that seemed to resolve the issue.

Microsoft seems to think that the problem was one or more mailboxes had deep seated folders in it and that is what caused the issue.  They have seen this problem before, but, they have not caught the exact cause of the issue.
