[ClusterLabs] pacemaker-fenced /dev/shm errors

[d tbsky]

Hi:
   the cluster is running under RHEL 9.0 elements. today I saw log
report strange errors like below:

Mar 27 13:07:06.287 example.com pacemaker-fenced    [2405]
(qb_sys_mmap_file_open)     error: couldn't allocate file

(check_active_before_startup_processes)     notice:
pacemaker-fenced[2405] is unresponsive to ipc after 1 tries

there are no more "pacemaker-fenced" keywords in the log. the cluster
seems fine and the process id "2405" of pacemaker-fenced is still
running. may I assume the cluster is ok and I don't need to do
anything since pacemaker didn't complain further?
