When I start corosync-notifyd -f -l -s -m <MONITORINGSERVER> and close it with CTRL-C, pacemaker make a shutdown. Please see below for the details. I compiled the current master of corosync (tag 2.1.0) and the current master of pacemaker. The OS is Solaris 11U7. Is this a feature or a bug? In Solaris libqb must be patched to avoid errors. Please see https://lists.fedorahosted.org/pipermail/quarterback-devel/2012-September/000921.html "[PATCH] -ENOTCONN handled as error when client disconnects" Maybe this patch should not deliver -ESHUTDOWN when a client disconnects. IMHO this is the adaequate result.

All the Pacemaker daemons are being told, by Corosync itself, that their connections to Corosync are dead. Its a little difficult to ignore that. > Is there a chance in pacemaker or should should this better solved in corosync/corosync-notifyd? It needs to be addressed in corosync/corosync-notifyd. Corosync's CPG library is the one invoking our cpg_connection_destroy() callback. > > Andreas > > -----Ursprüngliche Nachricht----- > Von: Andrew Beekhof [mailto:andrew@xxxxxxxxxxx] > Gesendet: Mittwoch, 3.
