I have 2 nodes that wont update their Jobque. I can't figure out why. All other nodes work fine and even these 2 can remote access the database on the master node. I can't really see anything wrong on the logs either. These 2 used to have Dovecot on them. That is the only difference between the rest of the nodes. When I use phpmyadmin and look at the "updated" on "server" table these 2 nodes show 16746 while the rest show the last correct 16877. What's the best way to start debugging this?
