BIG-IP LTM
Opened: Mar 08, 2016 Severity: 3-Major
Profile changes with certain configurations will cause a large number of internal transitions that will cause the update to take an excessive amount of time. The amount of time is dependent upon the number of iRules and SPDY profiles in use in the system.
When the amount of time is too excessive, this can cause the watchdog processes to think tmm is not responding and can ultimately kill the tmm and cause a possible failover event. When not long enough for the switchover daemon (sod) and watchdog processes to intervene, this can still lead to a traffic disruption.
Using iRules and SPDY profiles, and making updates to profiles.
