The standby system sends gratuitous ARPs on the standby system for virtual servers configured with message router.
Traffic is routed to the standby system instead of the active one, causing connections to stall/fail until the neighbor table is updated.
This symptom may occur if: -- The message router profile traffic-group is set to default (inherit from folder). -- The message router profile folder is also set to inherit from parent folder. -- A configuration change is made to the virtual server on the non-active unit.
Set traffic-group on the message router profile.
