[ClusterLabs] pacemaker-remoted /dev/shm errors

[Alexander Epaneshnikov]

Hello. we are using pacemaker 2.1.4-5.el8  and seeing strange errors in the
logs when a request is made to the cluster.

Feb 17 08:18:15 gm-srv-oshv-001.int.cld pacemaker-remoted   [2984] (handle_new_connection)      error: Error in connection setup (/dev/shm/qb-2984-1077673-18-7xR8Y0/qb): Remote I/O error (121)

other than that pacemaker/corosync works fine.

any suggestions on the cause of the error, or at least where to start debugging, are welcome.
