Hello, I have 11.6.0 Hotfix 6 and today I had same problem of failing over with the same error. Does anyone know the cause of this failover issue? It happened few months ago also. I opened a case then and I was told it is probably a networking issue which I am sure it is not. I opened a new case today, waiting for an answer. Thanks

    Hello,

    I'm confused, but we had a failover on 15.1.0.4 today when F5 switched twice and the symptoms are very simillar:

    HA reports tmm NOT ready.
Sod requests links down.
Failover event detected. (Switchboard failsafe disabled while offline)
Bringing down interfaces on links-up change

    Can you please, try to remember the support team answer? ASM is running on BIG-IP
