We have a multi-server install with separate DNS, Web, DB and Panel servers based on ISPConfig Manual. Recently, the System State was indicating incorrect versions of ISPConig installed on the various servers. We ran a resync of all services and the information is still incorrect. In addition, there are 134 sync operations that are now hung and will not complete. Also, one server needs to be completely deleted from the system manually, as the physical server is now out of service and cannot be brought back online. A new server was added to the cluster and it and is functioning. 1. How best to start troubleshooting the sync issues? 2. How do we remove the server that is no longer in service? Thank you for your help.
