SM Scheduler In Sync, Out of Sync counts

What does it indicate when a 450 SM has In Sync, Out of Sync, and Scheduler Error counts?

I am seeing a lot of reregs on SMs at one tower, all 4 APs. Which leads me to believe it has something to do with the GPS sync. And that the In Sync and Out of Sync counts are related.

Years ago I seem to remember something similar but that was on Canopy FSK. I think the fix was to replace an LMG CTM. Maybe it was the GPS antenna, but I think it was the CTM. The APs I am having trouble with now get their sync from a Packetflux Syncinjector.

Check your AP’s event logs for sync issues. If you AP’s are regularly losing sync, that can lead to SM’s being dropped.
