svchost.exe & ntdll.dll versions not the same

Had an issue with a MS clustered production SQL Server this weekend (2008 R2).  Approximately 2 hours after August updates were applied, the following event occurred which caused the data drives of the cluster to failover to the second node and left the quorum and DTC still on the primary node.

Faulting application name: svchost.exe, version: 6.1.7600.16385, time stamp: 0x4a5bc3c1
Faulting module name: ntdll.dll, version: 6.1.7600.16559, time stamp: 0x4ba9b802
Exception code: 0xc000071f
Fault offset: 0x000000000006e51c

My concern is to make sure this does not happen again and wanted to see if anyone else experienced any issues like this.  Also looking for advice on the versions, from what I am reading it looks as though these versions should be the same.  Could the version mismatch be the cause?

to find the root cause of the problem with dll or programs crashing/hanging, you generate a dumpfile using ADPLUS.
When examining this dumpfile the root cause can be revealed.

If you can't reproduce the error you'll most likely never find out why it hanged and what caused it. The ADPLUS tool is invaluable in a good technichians utilities box. You never know when you might need it the next time.
