Opened: May 01, 2018
Severity: 2-Critical


When the BIG-IP system comes up, or when tmm/dwbld/iprepd restarts, tmm does a flush of sPVA. If the operation does not succeed, the system can wait for 10 seconds, which might cause an abort due to heartbeat failure. tmm crash


tmm will have to be restarted. Traffic disrupted while tmm restarts.


-- BIG-IP system comes up, or tmm/dwbld/iprepd restart. -- HSB flush does not succeed within ~3 seconds (it is supposed to succeed within ~3 seconds unless something is wrong with the HSB).


There is no workaround at this time.

Fix Information

The system now checks asynchronously to determine whether or not the flush sPVA has succeeded.
