Hi, If Apache is gracefully rastarted multiplae times it dumps core. To reproduce this problem there is a script that can be run which sends a kill -HUP to httpd every 20 secs. The scpirt is
#!/usr/bin/sh COUNT=1 while true do kill -HUP `cat "path_to_httpd.pid/httpd.pid"` date "+DATE: %m/%d/%y %H:%M:%S count: $COUNT return: $?" COUNT=`expr $COUNT + 1` sleep 20 done If this is run as >nohup ./testhup.sh > testfile & produces the output as DATE: 11/25/04 17:09:38 count: 0 return: 0 DATE: 11/25/04 17:09:53 count: 1 return: 0 DATE: 11/25/04 17:10:08 count: 2 return: 0 Eventually it stops at dumps core. The error_log produces this [Fri Nov 26 04:55:43 2004] [notice] SIGHUP received.
