    Hey all,

    We had a switch stack reboot and when the switch came back, one of my APs did not. Checking the controller logs, i'm showing this:

    Apr 5 09:18:23 stm[9007]: <305061> <9007> <WARN> |stm| sapm_proc_hello_req: AP 10.4.33.19 b0:b8:67:ce:20:b2 GSM CLUSTER_AAC is not copied to assigned A-AAC, ignore HELLO
    (C-31-SA) [MDC] *#

    Any idea what this means or how i can clear it up? I think this is the root cause of it not coming back up, but not sure why I'm getting it. 

    We have a 2 controller L2-connected cluster supporting about 950 APs running 8.6.0.5 - VMM is running 8.6.0.6.

    Thanks!

    I found some additional things that may be related - the udbserver process is in a "PROCESS_NOT_RESPONDING-CRITICAL" state. I attempted to restart the process and initially it looked good, but went back into this state. I've scheduled a reboot of the controller after-hours and hopefully this will restore the process to normal functionality.

    mswitch/bin/udbserver PROCESS_NOT_RESPONDING_CRITICAL - 76 240 3 Mon Apr 5 12:38:25 2021
