Hi Carmen, We use the quiesce parameter of the reset command as well. I'm thinking that's what happened here as well, but we have no idea "whodunit". We had 1 operator on duty that day and he was off doing something else when it happened so the command made it into the system via an SDSF-like console session.

By freezing the system you disrupt all the online processing and you loose capability to find out what's wrong. I had to do with CPU hogging tasks and spool 100% filled by some ugly job. In both cases the very first thing to fix it was to logon to the system. -- Radoslaw Skorupka (looking for new job) Lodz, Poland W dniu 24.03.2021 o 03:30, kekronbekron pisze: > It's useful when you want to say "STOP IT!" to run-away CPU or spool jobs. > Will buy you some time to investigate. > > - KB > > ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ > On Tuesday, March 23, 2021 7:07 PM, Pommier, Rex <rpomm...@sfgmembers.com> > wrote: > >> Hey Carmen, >> >> At least you had an operator tell you what they did. :-) Once we determined >> what had happened (after a painful middle-of-the-day IPL) the only response >> I got back from anybody was "I didn't do anything like that!"
