Hopefully accurate summary
  386 box SCO 2.3.1 HDB talks to HP 9000/840 HP-UX 3.1 HDB
  errors of the form
>kdl ntcsd1 ntcsd1N0414 (7/27-XX:XX:XX,XXX,1) BAD READ (expected 'S' got FAIL)
  occur.

I've had these same symptoms occur with HP 9000/350 HP-UX 6 HDB talking to
HP 9000/8?? HP-UX HDB. Also same types of errors with 286 box SV/AT HDB
talking to HP 9000/8?? HP-UX HDB. TB+ PEP on HP 9000/8?? side at 19.2k with
no flow control and our side at 9600 with no flow control.  The symptom is
bad read followed by subsequent permission denied since the file was actually
transferred ok.  It seems to be associated with master/slave turnarounds.
Short files were mostly ok, longish files showed the problems.  I might
suspect the SV/AT or SCO HDB, but we have no problems communicating with
systems other than the HP 9000. Also, same symptoms in an HP-HP environment
tend to direct suspicions in other directions. Unfortunately, I didn't check
the 9000/350 -- SV/AT configuration when I had the chance.  Next time I'll use
a line monitor :-( Sorry for the lack of detail in this posting, I wish I had
more solid information.
