Fellow listers,

Our 969/220 got 'hung' sometime around midnight on Saturday.  Batch jobs
would get submitted by our scheduler but never begin execution.  There was
not much/any user activity on Sunday and thus no one noticed.  Then on
Monday folks begun to complain about being 'stuck' just after entering
their logon information, they begun getting informed that they were already
logged on and would not be allowed to establish another logon, etc..

I came in and tried to logon at the console with the same results.  I
finally had to reboot the system and, because of other pressures, did not
take a memory dump.  The system came back up and since this weekend was
month end/quarter we begun our full backup.   A couple of hours later we
were back in business with no data loss.

I spent the better part of this morning searching the log files and other
files on the system in order to determine what may have happened.  I found
a large volume of 'DTS-IIOM' and ordered a patch that is supposed to
address them, but nothing else.  Then this afternoon the following
suspicion begun came to mind and I thought that I would run it by the
collective wisdom of the list.

In our environment the users connect to our HP3000 through 2 DTC72MXs that
are under the OpenView DTCMGR control.  The DTCMGR software is executing on
a Windows 98 PC.  When I was re-booting the HP I noticed that the PC had a
'pop-up' window display, informing us about the time change that occurred
last Sunday (I know its over a week ago, but if you don't need to go in the
computer room....) and it was still waiting for someone to 'click' the "OK"
button.

 Is it possible that problems that we experienced were somehow related to
the DTCMGR software being interrupted by this 'pop-up' window and not
performing its normal tasks?

Regards
Paul Christidis
