Hi,
My server went offline in the night and I managed to fix it by rebooting the system.
Before rebooting, I was unable to ssh into the server or any jails.
When directly connected to the keyboard, keystroke was not recorded
I run a FreeBSD host based on 12.0-RELEASE and I have several jails running..
13x webjail
1x DBjail
1x webprox
1x mailjail
1x bhyve vm
When I looked at the /var/log/messages I have a lot of the following entries which reconcile with the monitoring tool showing the sites been down.
I looked at dovecot log on the email jail and found noting out of the ordinary
Could anyone please help me undestand what happened?
