I have created a cluster by following https://www.howtoforge.com/tutorial...abase-cluster-on-debian-8.4-with-ispconfig-3/ but with Ubuntu 18.04. Has worked great for a month or so. Yesterday suddenly the dns server on the slave was no longer up to date. I checked the MariaDb slave status and it was stalled. Then I did a slave reset and restart. Is now almost done syncing and I see the latests record in the dbispconfig database, but the dns server on the slave still has old data. Will the dns server update itself after a while? How does Ispconfig update things like dns and mailboxes on the slave, once they are changed on the master? I also notice there are 2 databases on the slave: dbispconfig and dbispconfig2. dbispconfig is (almost) up to date, but dbispconfig2 does not have the updates for the last 2 days. Why are there 2 databases? When and how does Ispconfig update dbispconfig2? Thank you very much for any help!
