This one is simple. Save command does its front-end processing in a job, but real work is done by LDxxxx task in a background. Job stays in EVTW waiting a report from LDxxxx task. This task has prioirity one less (numerically one more than your job). Now if you have other jobs in a loop with a priority higher than LDxxxx task, it will never have a chance to run. If you turn dynamic priority scheduler on, this will not happen, because looping jobs will get their priority lowered, and LDxxxx task will have its priority bumped with a result that it will eventually run and do its job. This is an excellent illustration why dynamic scheduler was introduced!

The DYNSCD is now turned off. I have three jobs looping (ALOOP). Every second they show a screen (with no wait) and YIELD their timeslice. Job 0007 is trying to save an object to a save file that already exists, and I had to type "G" to tell it to Go ahead. After that, the save is stuck in an EVTW. Job 0001 is sitting on a DSPW. I can interact with that screen with no wait at all. (This is on V4R5).

But why was the job stuck on the EVTW? _______________________________________________ This is the Midrange Systems Technical Discussion (MIDRANGE-L) mailing list To post a message email: MIDRANGE-L@midrange.com To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/cgi-bin/listinfo/midrange-l or email: MIDRANGE-L-request@midrange.com Before posting, please take a moment to review the archives at http://archive.midrange.com/midrange-l.
