WAC720 rebooting for no apparent reason
I have 10x WAC720 AP's in an ensemble, all on the latest firmware (3.9.1.13), and they seem to randomly reboot causing all connected clients to drop or switch to another access point. They don't all do it at once, though sometimes a few will go off at the same time or in succession. It seems to happen more often when there's a lot of people around with devices, but it has also happened when nobody is around and there's only ~3 idle devices connected. The AP's are powered from a mix of PoE switches (HP and Dell) and injectors around the building, all on battery backups.
I enabled syslog and checked it around the time of a reboot but nothing seems out of the ordinary. CPU utilization is low and memory is under 75%. They're all in very heavily air conditioned spaces so it's unlikely to be thermal either unless there's an internal problem. It's driving us mad and causing disruption to some of our operations, and I'd really hate to waste $1,000 +labor replacing all of these... but I'm running out of options.

have you been able to isolate it to a few devices or is it everyone of them?
Reason I ask is if you can isolate it to a few, maybe its the POE connection causing the issue.
with multiple devices having the same issue, I wouldn't be looking at a hardware issue with the router.
I'd either be looking at the firmware or whats powering them.
It is unfortunately all of them. Some do it more than others, but they all do it.
Did it just start recently or how long has it been going on?
I'd try downgrading the firmware and getting in touch with a mod from the business side.
If its a firmware issue, it'd be good for them to know.
Those devices do have a lifetime warranty but its doubtful that all 10 would have hardware failure at once.
