A vCMP host tmm is restarted.
The host TMM restarts and traffic stops for the guests.
The vCMP host is processing heavy multicast traffic.
An adjustment to the scheduling can be made by this setting of the vCMP Host configuration: # echo "realtime yield 90" > /config/tmm_init.tcl # bigstart restart tmm The bigstart restart tmm must be performed individually on all blades on the vCMP host. These changes also must be done on all vCMP hosts with guests in a high availability (HA) setup.
The host TMM no longer restarts.
