[net.bugs.uucp] increasing uucico's patience

henry (08/25/82)

When talking to a site which is heavily loaded and which has a lot of
traffic waiting for you, uucico times out fairly easily.  This is
particularly true if the site you are talking to does not have the bug
fixes I sent out some time ago for the imbecilic code in V7 anlwrk.c.
(The V7 anlwrk.c scans the entire directory even if it filled up its
work list early in the scan, and has some other time-wasting botches.
Some later uucp's have some of the problems fixed, but perhaps not all.)

Uucico's tolerance for sluggish neighbors can be greatly increased by
changing PKTIME in pk1.c from its distributed value (10) to something
more reasonable.  We have been running for some time with a PKTIME of
30 and have just increased it to 60 -- recent decvax outages have caused
a pileup of utzoo-bound traffic there, and decvax's uucp doesn't seem
to cope with it well.

There are several other constants elsewhere -- timeout counts and so
forth -- that look like plausible candidates for increases, but some
earlier experiments with that were total failures.  PKTIME is the thing
to bump.  To give proper credit, it was watmath!dmmartindale who first
tried increasing PKTIME;  I got the idea from him.
