A few months ago my R&D LPAR was creating thousands of QPWFSERVO jobs over a 2 hour window.
Noticed in QSYSOPR, QHST logs closing, quite often, every 7 seconds.
576 QHST logs were generated in this 2 hour window.
This pointed me to view QHST, where I saw the thousands of QPWFSERVSO starting and ending.
Based on the first and last message in QHST, using the job number as a reference, 292,571 QPWFSERVSO jobs started/end.

Root cause never identified, dead case with IBM support.

Subject: *SSHD Job generating joblogs every second

I have an open ticket with IBM but at this stage they are suggesting a test PTF for the issue which is going to take days.

The other morning I had a call from a site we look after where users could not sign on.

Below is the initial steps taken and details of two joblogs showing errors. Stopping *SSHD stops the issue.

The system generated over 160000 jobs which had joblogs *pending and exceeded the maximum jobs.

Anybody seen anything like this or have any comments/suggestions ?

System would not allow any new jobs as system tables were full.

Have increased MAXJOBS to allow new jobs to be started.

DSPJOBTBL F11 shows large numbers of joblog pending

WRKJOBLOG shows very large number of job(QP0ZSPWP) being created for user QECOFR approximately every 1 second.

Many of these are relating to CPFA09C Not authorized to object. Object is /QSYS.LIB/EN_US.LOCALE.
