VCMP guest shutdown can interfere with execution of the VCMP hypervisor TMM, causing 'Clock advanced' messages and TMM restarts wit corresponding core files.
Traffic disrupted while tmm restarts.
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.
Shut down vCMP guests one at a time to reduce the likelihood of encountering this issue.
Resolved occasional TMM restarts when stopping vCMP guests on 12050 and 10350N appliances
