Failover issues with MQ clusters

One issue we've had with MQ Series in a clustered environment is that if you initiate a failover to the passive node, and then failback, MQ Series will moan about Semaphore locking issues. This is a known issue with MQ that IBM is working on with Microsoft.

The solution (work around) is to always reboot the original node before failing back the resources. This seems to cure the issue!
