Symptoms

VCMP guest shutdown can interfere with execution of the VCMP hypervisor TMM, causing "Clock advanced" messages and TMM restarts wit corresponding core files.

Impact

Traffic disrupted while tmm restarts.

Conditions

VCMP guests in state 'deployed' are modified to state 'provisioned' or 'configured', or are deleted entirely. The likelihood of a TMM restart increases with the number of guests that are stopping at the same time.

Workaround

Shut down VCMP guests one at a time to reduce the likelihood of encountering this issue.

Fix Information

None
