I have seen random rsh failures on other systems - maybe it's a general
BSD bug w.r.t OOB data handling?  (Does rsh use OOB data?  I know rlogin
does).

You _could_ always run tcpdump -w from cron over that time period to log
what's going on (I mean, you'd probably be doing something like that
anyway, so there's no reason to be up for it :-) ).
