I had a strange weekend - what was it Jerry Garcia used to say "What a
strange journey this has been"?

We began having TCP/IP troubles on Friday - we could establish sessions, but
data transfers would hang after a few bytes were sent - they would timeout
either as a communications timeout, or an idle wait, depending on when TCP
decided to stop.  This didn't clear until 2:00 AM, when they bounced TCP/IP,
but operations didn't recycle ADSM, so we were out of the water until mid
morning Saturday when I happened to check it.

Nothing much unusual there, but here is what had me confused.  Sometime on
Friday, all of our Admin schedules stop executing - no indication as to why.
Around noon on Friday, I had operations recycle ADSM, which went
successfully.  When it came up, an admin schedule that was in the middle of
its window kicked off, executed, and reported back a successful completion.
I thought the problem was solved, but later Friday, I checked again, and the
admin scheduler was out again.

I cannot think of any relationship between  TCP/IP communications, and admin
schedules.  Does anyone have any ideas?

When I discovered the problem on Saturday, I again had them restart ADSM, and
again it seemed to take off - reconnected to TCP/IP, and admin schedules
seemed to be working.  Later that evening, though, not only had I lost
communications again, but console traffic seemed to be gone as well.  Since
we had an IPL scheduled for 7:00 AM Sunday, we decided to let it go, and
since the IPL, all seems to be fine.  We did have a bad tape - actually 2
tapes with the same TSN, but that didn't seem to contribute to this problem.
This was all under release 12 of the MVS server - We are now under level 13,
as it had been one of the planned upgrades on the IPL on Sunday morning.

Anyone else see strange things like this?
