Hi,
Yesterday evening we had a long running process that generated a ton of 157 wait events (13k events over two hours, totaling over 2500 seconds).
I tried to look at the cache statistics via MDA data, but nothing obvious stands out.
Does this wait event ring a bell?
This is a new server, running 15.5 (not sure which exact ESD), with 56GB allocated to the default data cache, and 7GB to tempdb cache, 30 engines on AIX hardware.
CPU usage during the problem time was low (less than 10% for most engines, except where this process was running), essentially only this process was doing anything significant on the server.
Many thanks!
Michael
