[gpfsug-discuss] mmsysmon exception with pmcollector socket being absent

[Frederik Ferner]

Hi Ragu,

have you ever received any reply to this or managed to solve it? We are
seeing exactly the same error and it's filling up our logs. It seems all
the monitoring data is still extracted, so I'm not sure when it
started so not sure if this is related to any upgrade on our side, but
it may have been going on for a while. We only noticed because the log
file now is filling up the local log partition.

Kind regards,
Frederik
