Nov 27, 2018
- Cisco Unified Computing System
Known Affected Releases
Symptom: The UCSM process (svc_sam_dme) had a condition due to which the main transaction thread deadlocks and cannot make progress. This will result in all communication from GUI or CLI to dme will fail. So any commands to look at managed objects from cli like 'show service-profile' or 'show server details' etc will show error message. GUI will probably stop responding and any operations like firmware upgrade, server discovery, etc more or less any operation from gui or cli will fail which will involve communciations with dme. Conditions: The deadlock will be mostly entered when doing a failover or upgrade/downgrade or when there is mgmt link flapping combined with ucsm ha failover.
