Symptom: After a volume based service software update failure, downstream recovery can fail when performed after an ESC failover. Conditions: The following workflow can result in latching this condition: 1> Trigger a volume based service software update. 2> An underlying VIM failure causes the software update to fail (one or more VM_ERROR_STATE are raised). 3> Recovery is triggered to recover the service. 4> Recovery completes and service VMs return to service (VM_ALIVE_STATE). 5> Send service update with ESC failing over before update completes. 6> Service update fails as expected. 8> Attempt to resend or revert (recovery) the service update (fails). 9> At this point service volumes can’t be managed so VM state can no longer be progressed. When this condition latches the following log will surface confirming underlying VM database access violation: ERROR: duplicate key value violates unique constraint "pk_vmstoredstatestable"
