Traffic disrupted on the BIG-IP that recieved the config sync while tmm restarts.


- In-tmm monitors are configured (bigd.tmm = enable) - Full sync is performed - Monitors are using a custom ssl profile - The ssl profile was changed as part of the full sync.


Disable in-tmm monitors, and avoid performing a full sync after modifying in-tmm ssl monitors.
