Last night, a service (zmamadvistctl) stopped on our production server. It then stops delivering any messages. I restarted this service using:
> zmamavisdctl start
This started the service but bogs down the server to the extent that I cant even SSH into it. I started it once this morning and it died 10 minutes later.
I was finally able to get through to it using ssh, and restarting zimbra through "zmcontrol stop" and "zmcontrol start" seems to have fixed the issue. (for now).
Is there a reason that this service would stop all emails from being received or delivered to individual mailboxes?
