 This has been happening here as well, with Apache 1.3.5dev.  I've got,
 in my httpd.conf, the line
 ErrorLog "|/usr/local/bin/aplog.pl"
 .  As you all probably know, apache sees this and runs it using /bin/sh
 as a wrapper, like so:
 /bin/sh -c '/usr/local/bin/aplog.pl'
 .  When apache gets kill -HUPped, it _does_ send the SIGTERM, followed
 by the SIGKILL to the 'sh' process, which dies, but then the aplog.pl
 process doesn't get killed along with it.  You can work around it by
 substituting
 ErrorLog "|exec /usr/local/bin/aplog.pl"
 for
 ErrorLog "|/usr/local/bin/aplog.pl"
 .
