PHP 4.0 Bug #6897: Oracle/PHP defunct Apache processes

From: sal@wiggum.com Operating system: Linux - kernel 2.2.14, glibc 2.1 PHP version: 4.0.2 PHP Bug Type: OCI8 related Bug description: Oracle/PHP defunct Apache processes PHP 4.0.2, Oracle 8i libs, Apache 1.3.12 Config script: './configure' '--with-mysql=/usr/local' '--with-apxs=/usr/local/apache/bin/apxs' '--enable-track-vars' '--enable-trans-sid' '--with-config-file=/usr/local/apache/conf' '--with-xml' '--disable-debug' '--with-oracle' '--with-oci8' '--with-gd=/usr/local' '--with-cybercash=/root/src/mck-3.2.0.6-i586-pc-linux-gnulibc2.1' '--enable-sigchild' When I compile in Oracle, and OCI8 support into PHP, it leaves a lot of defunct apache processes around. [libhttpd.ep <defunct>] I read on the mailing list a fix is to --enable-sigchild in php and compile apache with -lpthread, but that didn't work. A request to apache once there are these defunct processes around will just hang until apache is restarted, or those processes die out. There is no core dump. I have 80 of those in memory right now.
