This machine is a Perkin-Elmer 3220 running P-E's version of
UNIX version 7. The UUCP is v7 vintage, with P-E improvements,
and I've added all of the fixes posted to the net since 1983
that I've seen (we have source). We have about 50 uucp neighbours,
and process 5-10Mb/day over five phone lines at 1200 baud.
Quite often I find a hanging uucico, that needs to be killed
off by hand to free things up. This has been happening once
every few days. There are two "modes" this appears in; one
is on dialout, where it happens randomly when calling several
different systems. The LOGFILE shows nothing unusual; the
uucico seems to be in the middle of a file transmission. The
modem is still tied up, but no data is moved on the line.
In the other instance, on dialin, it only happens with one site
(attcan, an AT&T machine running SysV), but when it happens, the
uucico at this end keeps chewing up more and more CPU time,
although the call is dead.
Does anyone know what's going on here? Is there some easy
fix to the uucico timeout mechanism? (Yeah, I know, "get HDB".)
