I had the same message as my UTMs Postgres DB was inconsistent and damaged. 
 
 You may log into your UTM via SSH and type 
 
 ps auxf | grep postgres 
 
 you should see more than one or two lines here. If not there's something wrong with your DB. 
 You also should have a look into your system.log (you can access it via Webinterface, or via SSH by typing 
 tail -f /var/log/system.log 
 while logged in. 
 
 If you get messages that are pointing to a Database fail (it may is also visible in HighAvailability log) then you can try to restart your UTMs, or, you need to rebuild your DB. 
 But this you should let do the support from Sophos.
