I encountered the two following errors while running "uuxqt -x9". I would
appreciate any comments as to their nature. Thanks in advance.
1) This was the result of mail being sent to an unknown user-id. Do the
status/signal/exit values provide me with useful debugging information?
shio - PAT=/bin:/usr/bin:/usr/ucb;export PATH;rmail sri
Subfile with prefix:/usr/spool/uucp/sys/DEFAULT/D./D.ucdavisScBL2
status 17152
retstat is signal 0, exit 67:
2)
Subfile with prefix:/usr/spool/uucp/sys/DEFAULT/D./D.ucdavisScCA2
sh: 4960 Illegal instruction
status 0
retstat is signal 0, exit 0:
exit cmd - 0

Mail software, at least under BSD, tends to use a set of exit status conventions listed in <sysexits.h>. 67 is EX_NOUSER, "addressee unknown", which tells you it's mail sent to an unknown user ID. From your comment, though, I infer you already knew that. Also, unless you happen to know that those conventions are used, the numbers might as well be random. Those could be considered arguments that it's not useful debugging information.... (17152 is 67*256, or "67 in the next byte up from the bottom"; in other words, it's the same as "signal 0, exit 67" - see WAIT(2) - and thus redundant.)
