A reboot of the both systems seems to have fixed this issue.
Thanks for the help.

Kind Regards

Thanks for the help.
I'll try to arrange a reboot of the current DC. See if that fixes it.

I have this theory that
include/heartbeat.h:195:#define MAXMSGHIST      500
may be too low and may wrap (several times?) on a busy pacemaker
cluster, or if you have very low keepalive set, once you have "flaky"
communication problems for an extended period of time.

If someone has a way to reproduce this behaviour,
we could check if upping that define would "fix" it
(extend the period where heartbeat can cope with "flaky").

How to get out of there?
well...

First, get your comms in order.

Then, maybe restarting the "loudest" node helps?
Or on both? Or on the node that does _not_ log those messages?
Dunno... never seen this myself.
Though there are sporadic reports of similar messages in the archives,
and mystical "workarounds" involving the deletion of some files of which
I very much doubt that have anything to do with this particular "Rexmit"
message...
