Wondering if anyone else is seeing this problem.
We've experienced problems with after updating controllers to 18.104.22.168
All APs on a controller will rebootstrap after a period of time, usually less than 48 hours. Ap debug info shows heartbeats missed and the reason for disconnect as: controller aged out
We've rolled our live controllers back to the previous version (with the ARM memory leak) for now and have a couple controllers on test. The problem occurred on one of the test controllers over the weekend, the rest of our 1900 APs were just fine on the older code.
We believe there's a bug in 22.214.171.124 and we're in conversation with support about this. Currently we're being told nobody else has reported this problem, so thought I'd ask here... Shout up if you've seen it.

We're on 126.96.36.199 and cirrently testing to see if a bug from earlier versions is present where all the
APs would fail over due to a missed heartbeat, whether or not there actually were missed heartbeats.
This would be the second time we were told it was fixed, the first time it did not go so well.
If this same bug has resurfaced in 188.8.131.52 after we finally have a verified fix that would be poor.
Maye move this thread out of the NAC forum? It is only by luck and boredom I even noticed it here.

Interesting... Without knowing how our setup compares to yours there may be other issues, I believe we're using vrrp between two controllers and this seemed to be the cause of our problems last time. Symptoms are slightly different now in that we can find nothing anywhere to suggest there's a problem. Previously we had DMA counters increasing on the controllers. Now everything looks fine until all APs on one controller rebootstrap. Not cool when it's about 1000 aps.
I have absolutely no idea how to control where things post in this forum, or how to move a post.
