Hello, first step is usually a packet trace, e.g. with ngrep. Have a look what is actually send and received for the DMQ protocol on the two Kamailio servers.

Hi, I have two Kamailio presence servers running version 5.8.4. I am using DMQ to synchronize the active_watchers and presentity tables, but the synchronization does not seem to be occurring consistently. During investigation, I observed that the DMQ status repeatedly toggles between active and pending, even though there is no packet loss detected. Output of dmq_nodes: { host: 192.168.18.96 port: 5070 proto: * resolved_ip: 192.168.18.96 status: pending last_notification: 0 local: 0 } { host: 192.168.18.99 port: 5070 proto: * resolved_ip: 192.168.18.99 status: active last_notification: 0 local: 1 } Any suggestions on what could cause this behavior would be greatly appreciated.
