Ohmigosh, I can't find it!

[stan at clyde.UUCP]

After the following shell script ran for five or six times, I got
the message "I can't find it!" followed by a carriage return.
I couldn't find that string in the shell (esh), echo.c, ps.c, or sleep.c .
Although I didn't try real hard, I couldn't get the problem to repeat.
Anybody got any ideas??

{shell=esh, system=system V,  mach=vax 11/780}

	while true
	do
		echo `ps -el|grep -c '^....R'` "  \c"
		sleep 1
	done
