AP7522 rebooting randomly

[TomasBDG]

Hello,

I have an above 20 access points AP7522 (firmware 7.4.1.3-006R) connected to the WING controller (firmware 7.4.1.3-006R).  One access point since few days is rebooting randomly. I excluded issues on PoE port on switch and potential issue with cable.

I noticed a strange log on this access point. The time of below log is the same time, when access point starts reboot.

Logs:

I didn't find on extreme community similar problem. Could someone help me with this? Waht this log means?
