Ok, this got it built, thanks for the tip. :) Unfortunately, the
new cron didn't solve the problem. Using sources from 2.2.2-Stable (8/18)
I got the exact same effect when it was necessary to start adjkerntz.
Here is the cron job:
*/2 * * * * root /bin/sh /root/test.sh
Here is the sh script I was using to test:
#!/bin/sh
/bin/ps -ax | /usr/bin/grep [a]djkerntz
ec=$?
if [ $ec != 0 ]; then
/sbin/adjkerntz -i &
fi
exit
And here is what got left over when adjkerntz was not running, and the
script had to start it:
15658 ?? Ss 0:00.01 /usr/sbin/cron
15685 ?? S 0:00.00 /USR/SBIN/CRON (cron)
15686 ?? Z 0:00.00 (sh)
15692 ?? Ss 0:00.00 /sbin/adjkerntz -i
As before, a kill for 15685 eliminated the zombie too.
I tried this with some other processes (named, snmpd, ircd) with
and without command line arguments, and with and without an & at the end
of the line to bg the process, and I didn't get any artifacts like the
ones above. Also, I tried it with a stock 2.2.1 system and started named
instead of adjkerntz, and didn't get the artifacts with that either,
although I'm seeing them on a 2.2.2-R system when a process is being
started from a perl script too.
It'll still be a few days before I can set up a 2.2.2-Stable
system, but if there is anything else I can do to test it, let me know.
