[SR-Users] DMQ Cluster - hosts loose network connectivity

[Charles Chance]

Hello,

DMQ will remove nodes from its internal list if they fail to respond to its
pings - with the exception of the original notification peer specified in
config. This way, if the network connection is lost, DMQ will continue to
try the original peer indefinitely until connectivity is restored, and
rebuild its list of other nodes from there.

Was the original peer (or one of them if multiple defined A/SRV records)
still active at the time of reconnection?

It would help to diagnose if you can you send your log from around the time
of disconnection, and also at the time of reconnect.

Regards,

Charles
