Well, it looks like the intervening "ignore SIGTERM" action is the /bin/sh
spawned as the parent of all syslog-ng children (v1.6.2, line 112 of
afprogram.c).
Sorry I didn't think of using truss/strace sooner. I've included the truss
output below. The command line used was "truss -d -f
/usr/local/sbin/syslog-ng 2>&1 | tee debug1.txt", so each line has the pid
and the offset-timestamp. You'll see that the /bin/sh ignores the SIGTERM
and keeps waiting for it's children. It was only after I SIGTERM'd sec.pl
did the /bin/sh exit. The processes were laid out as follows:
14340 /usr/local/sbin/syslog-ng
14342 /bin/sh -c /usr/local/sbin/sec.pl -intevents -input="-"
-conf=/usr/local/etc/se
14344 /usr/local/bin/perl -w /usr/local/sbin/sec.pl -intevents -input=-
-conf=/usr/lo
I sent the first SIGTERM to syslog-ng at timestamp ~7.5 seconds, where it
exited and /bin/sh didn't.
I SIGTERM'd /bin/sh at timestamp ~17.4 seconds, with no result.
It was only after SIGTERM'ing sec.pl at ~23.4 seconds did /bin/sh give up at
~26.4 seconds.
I'm not sure what to do at this point about the /bin/sh - but I'm open to
suggestions. I've checked syslog-ng 1.5.26 that Nate said he was using and
it has the same /bin/sh line in afprogram.c. I've found this info from the
'sh' manpage:
Signals
The INTERRUPT and QUIT signals for an invoked command are
ignored if the command is followed by &; otherwise signals
have the values inherited by the shell from its parent, with
the exception of signal 11 (but see also the trap command
below).
But I'm not sure what it would inherit from syslog-ng.

Ah yes! ok!
Once again, thanks for the help.
