I am running apache-ssl Apache/1.3.19 Ben-SSL/1.44 (Unix) and
have set up the error log to be piped into a perl program (called
a_iface.pl which waits for input from STDIN and sends it to another
process via a TCP socket). Occasionally the perl program receives
an EOF from Apache and dies, but no new process is restarted. I've
tried to test it by starting Apache, then using ps to find a_iface.pl
and killing it. I get something like:
root 3328 3327 0 11:37:37 ? 0:00 /bin/sh -c
/home/lam/bin/a_iface.pl
root 3324 1 1 11:37:34 pts/3 0:00 perl
/home/lam/bin/a_iface.pl
root 3329 3328 1 11:37:37 ? 0:00 perl
/home/lam/bin/a_iface.pl
If I kill the two perl processes, all die and Apache continues on
without doing any more logging as far as I can tell. No new
processes are created.
What do I have to do to get the "reliable" piped logging? I've read
what documentation I can find. It mentions restarts occur only if the
program crashes - how does Apache perceive a crash? Does it have
to send some sort of signal to its parent? Does my program have to
exit with a particular code? I've made it exit with a non-zero code,
but it doesn't make any difference. The only way I seem to be able
to get new processes is to restart Apache myself.
