AP Reboot: errno 2
We have a few APs that reboot with a 'heartbeat' lost message, although sometimes it's 'application reboot' in the web interface (of the ZD).
There's nothing obvious in the AP supportinfo file other than it lists reboot_reason: user reboot instead of the above reasons.
This is what the syslog output shows at the reboot time:
Jan 30 15:15:59 wireless4 stamgr: stamgr_AP_xml_house_keeping():complete updating ap cfg to emfd
Jan 30 15:16:00 wireless4 syslog: Request():IPC connection close. errno 2
Jan 30 15:16:00 wireless4 syslog: Request():Deplete everything in the pipe... TODO

Any insight as to what these syslog messages mean? Specifically what causes errno 2?
I had a support call open a few months back but couldn't replicate it reliably and it disappears most of the time when we move one of the rebooting APs to a new drop. It's almost like some APs are more picky about locations (power dips maybe?), because another AP moved to the same drop will be fine.
I should add that I've tried fw force-update on the rebooting APs with no luck.
