strange uucp message

[Mike Wescott]

We are running SysVr2 uucp, and occasionally we get the following
message mailed from cron (which has kicked off polling one of our
machines):
	
	r short 2 want 3
	rcount = 0
	xcount = 0

The message comes out of pk0.c and is clear as mud, can anyone
shed some light on this? What's it mean? I assume it's one of
those things that "can't happen but here's a message just in
case it does."
