Hmm, without doing anything, the messages stopped by themselves ;) Thanks

I guess there is a HA task being scheduled for a VM that may no longer exists or something similar. If you believe you haven't performed any manual DB updates prior to this then this NPE should be treated as a defect and you should file a bug report for the same.

We run ACS 4.4.2 with 5x XenServer 6.2. Can I fix this somehow? Thanks Martin
