[Pacemaker] ocfs2_controld.pcmk process issue

Hi!
I ran into the issue of ocfs2_controld.pcmk consuming vast CPU again -
twice, actually. The most recent happenstance was after a multi-node
failure. One node stayed alive, two nodes had to be rebooted. After
the reboots, one of the two came back without issue, and was able to
mount the OCFS2 stores. The second node exhibited high-cpu usage on the
ocfs2_controld.pcmk process, and could not mount the OCFS2 stores. The
logs were being voraciously filled with the following message:
ocfs2_controld: Unable to open checkpoint "ocfs2:controld": Object
does not exist
This message was being output so frequently that syslogd was starting to
rate-limit it. I suspect this accounts for the high CPU usage. After
restarting the troubled node several times, I found the solution was to
order the OCFS2/DLM resource group to stop, cluster-wide, and then
restart it. Normal behavior followed. (In a prior post to the list, I
referenced hard-killing the ocfs2_controld.pcmk process. This was a
more graceful shutdown.)
Attached are two strace outputs. I'm sorry I'm not very familiar with
strace, so the value of these files may be questionable. If there is
anything else I can provide the next time this happens, I'd be happy to
do so! The log-f.txt file was generated with the -f option, and the
log-fc.txt file was generated with -f -c.
Here also is a snippet from the syslog, during the cluster-wide shutdown
of the OCFS2/DLM group:
May 14 15:22:13 gw05 ocfs2_controld: Unable to open checkpoint
"ocfs2:controld": Object does not exist

One other interesting bit of log (well, to me), was this bit that
occurred when I tried to manually mount the OCFS2 store on the afflicted
server:
mount.ocfs2: Unable to access cluster service while trying to join
the group
One other note - I discovered I had not specified a monitor for either
the pacemaker:o2cb or the pacemaker:controld RA. Could that have
possibly triggered this issue?
