Ok, let me try to decode this cryptic description.
1. srlaser9 points to port 9101 or port #2 on the EX3 print server.
2. The error messages occur only sometimes with no obvious pattern.
3. The error messages ONLY occur with the printer on port #2.
4. The only email error messages appear from srlaser9.  All the other boxes
and ports apparently work normally and don't complain via email.

Is this correct?

My Unix and Linux Troubleshooting E-Book will show you how to
solve tough system problems!

If you flashed it within the last year, it's probably current.

If you have SNMP running, invoke:
        getmany printer_ip public iso
and you will buried in MIB variables and values.  The firmware version
should be on the top line under sysDescr.0.  I forgot the exact OID number
or I would have supplied a "getone" command that only returns the desired
variable.  For instructions on how to make SNMP work on OSR5, see:
  http://www.cruzio.com/~jeffl/sco/snmp_install.txt
Try it.  You might like it.

Good.  Now check that the values imbedded in the spooler scripts match
those in the Tech Article.  It's rather odd that only port #2 *SEEMS* to
having problems.  My guess is that either the port is fried on the EX3 in
question, of there is a typo error in the script where the 9101 port number
is defined.  Watch out for imbeded backspaces and invisible control
characters.  Since you apparently have other EX3 print servers available,
swapping boxes and reconfiguring the IP's will help point the finger to
either the box or the Unix configuration.

Remember: Assumption is the mother of all screwups.
