If a BIGIP has more than 12 tmms and one of the tmms above the 12th one loops due to a bug, it will loop indefinitely.
Traffic will no longer be accepted on that tmm that is looping indefinitely.
Another bug that causes a tmm to loop and it has to be a tmm greater than the 12th tmm.
Manually change /defaults/daemon.conf to have the correct stanzas for the remaining tmms. This change must be performed across every blade in the chassis. After performing the edit, load the changes into the running configuration via "tmsh load sys config partitions all", and then verify that sod is now correctly monitoring TMMs above tmm12, via a command such as: tmsh show sys ha-status all-properties | grep "daemon-heartbeat" | grep tmm
TMOS now monitors all tmms for looping/locked on systems with more than 12 tmms.
