Description (partial)


A RAP or MAP will randomly start reporting:
"Unable to transmit mesh adjacency frame"

During this time the Parent AP will not accept any Children and must be rebooted.  We did see
the issue clear itself randomly while troubleshooting.  This appears to be related to the Child
APs encryption keys disappearing from the Parent.  This was seen using remote debug
"keyShow" and "sibAgingShow".  These are all 1510 APs.
