In the telnet interface turn on debug then (if still supported) run
LLDCLI DSPOOL AUDIT
give the results to Prod Supp.
I'm pretty sure sastats and slopoke are gone, but donno about others. Is the LIST command structure still supported and would any of those help?
Maybe turn on the kernel monitor and then watch the SW logs for an hour or so during peak traffic hours.
KER CO(ontinuous)
KER STOP
I forget the interval the kernel reports are put in the SW log, every 15 mins or so seems I recall. Been awhile
There's some snapshot commands to use for an instantaneous peek at the queue, store and pool, but I would suggest letting PS guide you through those, some commands with a fast ker poll rate can create the same symptom you're trying to diagnose and bring a system to its knees.
