Hello,
We have suffering the same issue that this mate:
Re: Horizon View 6.1.1 pool with persistent disk
We have experiencing the same situation every X days. We have restarted cycle of VMware Horizon View environment and fixed provisionally, but the same issue appears for every Detach operation.
Do you know a final solution?
The posting appears to be answered, listing a number of queries to run against the DB to clear the entries.
Once we have done reboot cycle of VMware Center Server, VMware View Composer and VMware View Servers, the issue is solved. Along the time, after we do some detach operation, the issue appears and it isn't solved until we repeat reboot cycle operation.
We want to avoid this in the future.
