I've got 3 PMP 450m APs. The first two were running 15.0.1, and they seem quite stable. The third was installed with 15.0.2, and is now running 15.0.2.1 - this one has been randomly dropping sessions.
One of the recurring thing I'm seeing in the SM Session Logs of the SM which do drop a lot are things like this:
02/08/2017 : 00:02:12 CST : Event: SMSESFAIL, MsgType: REGREQTOMAXERR, NewState: OOSERVICE, Flag 0
02/08/2017 : 00:02:34 CST : Event: SMSESACTIVATE, NewState: REGISTERING, Flag 0
02/08/2017 : 00:02:37 CST : Event: SMSESMSG, MsgType: REGREQTO, NewState: REGISTERING, Flag 0
repeated 2 times
02/08/2017 : 00:02:43 CST : Event: SMSESFAIL, MsgType: REGREQTOMAXERR, NewState: OOSERVICE, Flag 0
02/08/2017 : 00:03:01 CST : Event: SMSESACTIVATE, NewState: REGISTERING, Flag 0
02/08/2017 : 00:03:04 CST : Event: SMSESMSG, MsgType: REGREQTO, NewState: REGISTERING, Flag 0
This particular SM reports its Air Delay as "38050 ns, approximately 3.541 miles (18701 feet)" (AP Range is set to 15 miles)
I notice under Statistics-> Scheduler that the "Scheduler Error" field increments when these issues happen. Signal quality is not great, but reasonable, and Spectrum Analysis didn't show any noise. Any ideas?
