We had an anomaly with our HP3000 system this morning.  When I got the call just beforee 5 AM, I could ping the server and connect to the remote console yet I could not remote in using either telnet or NS/VT.  I had someone go onsite (the server is located remotely from me) and the console was non-responsive.  Control-B worked, but going back to the console it was still non-responsive.  I finally got the console working via using Control-A and then hitting return (no Control-A command), and then the flood gates opened and hundreds of console messages flooded in.
 
At that point I could see what jobs were running and everything looked okay, with the exception of them running hours later than they were expected to run.  Looking at the $STDLIST for the restart job that runs after the backup (and which streams all the nightly batch jobs), I find this:

And what puzzles me about this is the elapsed time between the :LISTF and the SHOWJOB (1:31 AM to 7:34 AM).  The latter time is, interestingly enough, just about the time I got the console to start responding.

So, my question is:  How can I find out what happened to delay things from 1:31 AM until 7:30?

TIA
