I recently ran into an issue where the frequency of mmsysmon polling (GPFS 4.2.2) was causing issues with CCR updates. I eventually ended decreasing the polling interval to 30 mins (I don’t have any CES) which seemed to solve the issue. So, if you have a large cluster, be on the lookout for CCR issues, if you have that configured.
