Hello,
we have two 7240 controllers on dual mode with HA-lite setup, running 6.4.2.3.
when the APs miss a few heartbeats (~10sec) they try to failover, but when the connection is restored the APs fall into a state, where they are assossiated with their original master but user sessions are tunneled to the controller who was their Standby and clients are stuck in logon status.
We have removed Backup LMS configuration and also tried with and without controller state-sync with no success.
Aruba TAC has been contacted, but haven't given any solution yet, so I 'm wandering if anyone had a similar problem and if he can propose something we could try.
I can see some errors in:
