IBM has released PTF MF60348 to resolve this issue, requires an IPL though.
Other important and critical PTFs appeared in yesterday's SF99711 order.
DESCRIPTION OF PROBLEM FIXED FOR APAR MA44713 :
-----------------------------------------------
EL-ERRLOG task using significant CPU.

Subject: RE: PAL Log Analysis Report 63A0FFF6 Stat - 2000+ entries per night
Jim,
Here is the answer on the FFF6 stats.
"During a save or restore a FFF6 entry will be automatically generated whenever 2.3 GB of data is read/written to log bytes read/written counts and error rate info.
There was a bug in the error logging code that was incorrectly filtering out FFF6 entries, so loading new PTFs could explain the change.
If they are saving large amounts of data then thousands of FFF6 PAL entries are normal/expected.
The tape stats are used by applications like BRMS that track byte counts."
Many may not see these, when viewing the PAL, you must change Statistics default from N to Y.
IBM now has 3 other customers with the EL-ERRLOG log issue from my other thread, appears they may be related.
Should know more tomorrow.
What is interesting about the EL-ERRLOG issue, is you could have it and not even know it.
WRKSYSACT, look for EL-ERRLOG, taking around 30% CPU..

Jim,
Library and all drives on latest firmware code.
I remember these on previous hardware, P5 and LTO3.

I agree they may be very well connected. I see a few of these types of message occasionally but never in the quantity that you're reporting.
The other option to look at is the tape library and tape device firmware.
How recent is it? A fast easy non-disruptive way to see if it's related is to update the library and tape drive firmware.

Jim,
Below is the detail for one of the errors.
I questioned this decades ago, was told this is normal, informational only.
Does anyone see at least some of these?
If not, is there a tape setting (BRMS or non BRMS) that tells the machine to log these?
However, I'm thinking if this number reaches some sort of threshold, this could be the cause of my EL-ERRLOG consuming 30% CPU.

No, I've not see anything like that before. I think it's a call to IBM.

Is it normal, while a save is running, that 3 to 10 63A0FFF6 Stat (Tape volume statistics log) are written to the PAL every minute.
Resulting in approximately 2,000 63A0FFF6 Stat messages every night.
