We had a re-occurrence of the EL-ERRLOG issue, started 6/18 23:50..
I IPL'd with recommended PTFs applied.
Monitoring.
Both issues started around the same time, 23:40 to 23:45.
By drilling into a performance graph, I was able to see the system task EL-ERRLOG, consuming CPU resources.
Both on June 9, and June 18, 23:40 to 23:45, system task began taking more CPU, by 23:50 taking 30% CPU.
My question is, is there a specific job or process that may be triggering this issue?
I don't feel this was a co-incidence that on two different nights, the issue started at the same time.
Most monitoring software does not handle system tasks.
Using WRKSYSACT to an outfile, I'm creating a monitor for system tasks.

The problem got worse over the weekend.
Intermittent SSL failures.
Recycled an app to correct, app would not start.
Just IPL'd.
IPL resolved all issues.
Update from IBM.
Just heard another R710 customer had hit a lot of 18000061 VLOGs.
However, they have IASP, external storage, and PAL entries on their
2107 DASD.
We have some comparing to do between yours and theirs, and we have a development team identified.

Chuck,
Waiting on IBM development.
Hopefully they find something in the logs.
Possibly they may do a remote.
Not impacting production as of now, so I am going to delay the IPL, if needed, until I hear back from IBM.

Is there a way to end this task, EL-ERRLOG?
Or, do I need to IPL?
AFaIK the only resolution to the EL-ERRLOG utilization is to resolve whatever is the issue for which the VL18000061 is being logged, or to IPL and hope that whatever is the origin is resolved and does not simply restart due to the same origin after the IPL completes. There may be a LIC incantation to adjust the priority of that task. I would suggest a service\support call to the service provider to get support from IBM to research [and hopefully resolve] the issue before an pwrdwn\IPL; if not resolved, that hopefully they would at least be able to suggest if\that an IPL would resolve and anything that might need to be done to prevent the issue on the new IPL.
