Hi guys, Been battling this issue for about 2 weeks now. Some guidance would be much appreciated. Bought the ISPConfig manual hoping there would be some more details on debugging in there but unless I missed it it wasn't in there. I have the following nodes running: web (master db) web2 db mail ns After upgrading them all to 3.1 branch my job que no longer processes. I have read all the threads I can find in debugging this with no success. What I would like if someone that knows ISP config internal could lay out for me some details on what happens in the background for synchronization to occur and I am competent enough on the command line and with mysql to be able to figure it out I hope. For instance when I add a client on the master node (web), I am assuming it now writes that to the database on web, then via cronjob on each node say mail node will connect to master db, check the sys_datalog table and see if there is any information that it needs to add to its local db as well? I have tried running server.sh manually on each node, none produce any errors. I have tried increasing updated column in server table to completely clear job queue only to end up in the same situation again once new changes are applied. mail node did not have (for some reason) the ip and mysql information for the master db in it's /usr/local/ispconfig/server/lib/xxxx_config.php, I added that in but not sure how to force it to reconfigure itself? (I ran php -q update.php after those changes but no luck there either so far). I made sure that on the master db all servers are allowed to connect (and tested via command line mysql -h web -u root -p) from each host... that works... If anyone has any clue of what I missed I would be greatly thankful! Thank you.
