Screencast suggests hang is about 20secs after pmcd start, which is interesting and suggests it is NOT an initialization error, but possibly pmFetch related or some self-timer driven event in a PMDA. Was pmlogger enabled on this system? Another possible approach is trying to find the PMDA that is responsible (it is unlikely to be pmcd itself). You have 11 PMDAs in /etc/pcp/pmcd/pmcd.conf ... I'd start by commenting about half of them out (insert a # at the start of the line) especially the ones with low-level hardware contact or deep kernel contact, e.g. perfevent, jbd2, nvidia, slurm, xfs, linux, proc. Then try again. If this survives, you may be able to binary-chop your way to identifying which PMDA is the culprit. — |
