Hello sun-managers:
Thank you for all fifteen responses, most of which were bull's-eyes.
Briefly, the problem concerns printcap entries for "dummy" printers,
which had lp=/dev/null, resulting in periodic "waiting for lock on
/dev/null" messages. The solution is to create new null devices for
each dummy printer, and change their printcap lp entries to point to
the new devices. Also, don't use /dev/null for any printers, as this
can result in conflicts with other (non-printer related) software.
Warren Stokes had one of the most succinct answers, and his electrons
probably travelled the farthest, so I will extract from his here:
