My 'eximstats' appears to be down and fails to start on boot. I have tried to restart it via WHM and it still fails.
1 fix to try is to run the following commands as root via SSH.
This updates the missing MySQL Client libaries and completed the setup for eximstats.
If this does not work you need to create the missing 'eximstats' mysql account which is used to store and access the data for the 'eximstat' application. Sometimes you may also need to create the missing SQL tables and other data.
