AdGuardHome Shutting Down

My AdGuardHome plugin is shutting itself down, every day or so. It is not usually at the same time.

The jail appears to be running, I can get to the shell. I can then enter # service adguardhome start and it starts up.

Can someone point me to some troubleshooting ? Is there a log file anywhere that might point to a cause ?

Is there a way to auto-start the service if it stops ?

Thanks for any help.

George.
