Some vSphere Replication operations might take a long time to complete during a heavy load.
Operations such as recovering virtual machines fail with the following error:
Object object_GUID is locked by another ongoing operation in vSphere Replication Management Server. Try again later.
When running under heavy load, some vSphere Replication operations might take a longer time to complete and other operations can fail with this error because a background update operation on the replication group is slow and holds a lock on the replication for a long time.
Retry the failed operation after a few minutes.
