{6.10.3} AdguardHome docker container randomly stopped in the middle of the night

Hi all, 

Recently upgraded to 6.10.3. My containers and system have been remarkably stable in general. However, last night when my auto-update process started at 2am a few errors were thrown that included my DNS server AdguardHome being taken offline and not restarted.  syslog below and diagnostics attached. Ideas on what might have happened?

Thanks!
