I'm having an event occur on my system this morning that I'm still trying to understand.
The faulting rate in the system *MACHINE memory pool skyrocketed.
I've seen this happen before when a communications recovery is in progress, but I checked that out and our comm interfaces seemed to be performing just fine.
I did notice that a couple batch jobs were doing big query sorts (QQQTSORT) .. and when they ended the faulting rate tapered off for a few minutes. But it is still at about 9.8/second with an allocation of 11GB... That is high. We usually can run at 2 faults/second with about 2GB allocated.
Does anyone have any ideas on what I might look at to determine what is going on here?
