Previous Comments: ------------------------------------------------------------------------ [2002-08-02 11:38:06] jason.mccormick@lexi.com I've been experiencing this issue on a production webserver since I upgraded the client to Oracle 9i. Previously, the install worked fine when the client was Oracle 8. I tried this out on my development box and everything works fine. The production box is running: Linux 2.4.2 (early RH 7.1 or 7.2) glibc-2.2.2-10 gcc-2.96 My development box is running: Linux 2.4.18 glibc-2.2.5 gcc-3.1.4 Both machines are running Apache 1.3.26 with pthreads. Both have the Oracle 9.2 client. PHP was configured in both cases with: ./configure --with-apxs=/opt/apache/bin/axps --with-oci8=/opt/oracle --with-mysql=/opt/oracle --with-gettext --enable-track-vars --enable-force-cgi-redirect In both cases, Apache was compiled with: ./configure --prefix=/opt/apache-1.3.26 --enable-rule=SHARED_CORE --enable-module=so --enable-module=rewrite and then later recompiled with pthread w.r.t. to the OCI8 directions. I cannot seem to get a gdb dump trace from the production box (probably becuase of missing development tools) but it does generate a core file if someone is interested in me sending them output from that (e-mail me at jason.mccormick@lexi.com and give me instructions). Please advise how I can help debug this issue as it is critial to me. ------------------------------------------------------------------------ [2002-07-26 20:40:00] chs@baltic-online.de The same issue was experienced on sun-sparc-solaris2.8, with Oracle 8.0.5. Both php 4.0.4pl1, 4.0.6 and 4.2.2 are affected. Please, solve this issue as soon as possible - this is a serious showstopper. Thanks! ------------------------------------------------------------------------ [2002-07-25 05:25:24] thomas@fivemile.net Configure Command './configure' '--with-db' '--with-apache=../apache_1.3.26' '--with-gd=../gd-1.8.4' '--with-mysql=/usr' '--with-zlib' '--with-oci8=/home/oracle/product/9.0.1' '--enable-debug' '--enable-track-vars=yes' '--with-jpeg-dir=/usr' '--with-tiff-dir=/usr' '--with-png-dir=/usr' '--with-xml' '--with-calendar' '--enable-sigchild' '--with-xpm-dir=/usr/X11R6' '--enable-calendar' '--with-ttf=/usr' [root@einstein src]# gdb ./httpd GNU gdb Red Hat Linux (5.1-1) Copyright 2001 Free Software Foundation, Inc.
