We're running SunOS 4.0 (plus the "general hygiene" patches) on a 3/280.
I was interested in learning just what an <exiting> process was, so I
tried using "gcore" to get a dump. Serendipitously enough. . .
elsie$ /bin/su
Password:
elsie# ps -l#22255
F UID PID PPID CP PRI NI SZ RSS WCHAN STAT TT TIME COMMAND
8601 0 22255 1 0 3 0 48 0 lbolt S h4 0:00 <exiting>
elsie# kill -9 22255
elsie# ps -l#22255
F UID PID PPID CP PRI NI SZ RSS WCHAN STAT TT TIME COMMAND
8601 0 22255 1 0 3 0 48 0 lbolt S h4 0:00 <exiting>
elsie# gcore 22255 &
[1] 26519
elsie# [1] + Stopped(tty output) gcore 22255 &
%1
gcore 22255
gcore: 22255 exiting - not dumped
elsie# ps -l#22255
F UID PID PPID CP PRI NI SZ RSS WCHAN STAT TT TIME COMMAND
elsie# exit
elsie$ exit
Of course this gcore behavior probably changes in 4.0.1 or 4.1.

[[ I wouldn't be so sure. An exiting process usually doesn't even have
any allocated memory left to gcore. --wnl ]]
