"Restarted by CaOs"

I have this message on some 450i AP's (in different towers)

I've never heard this message before... what's mean?

Thank you!

Hi

Please share us the CNUT logs at support@cambiumnetworks.com to check what might be causing the issue.

I have attached the steps to download the CNUT logs. 

Done

Thanks

Also for me. I have to send the log via mail?
