Fixed In Version: ovirt-engine-4.2.3
Doc Type: Bug Fix
Doc Text:
Cause: The access to an external network provider is enforced to be serialized be non-blocking locking. Consequence: If an external network is added, removed or imported during the automatic synchronization of the same network provider is running, the adding, removing or importing is failing with a message like: "Cannot add Network. Related operation on provider with the id c38a67ec-0b48-4e6f-be85-70c700df5483 is currently in progress. Please try again later." because of the automatic synchronization holds the lock. Fix: Use blocking locks to Import, Add and Remove external networks. Result: Network is added successfully after the sync is finished.
