Bug #12085 Updated: few apache children crash the system

ID: 12085 User updated by: denis@edistar.com Reported By: denis@edistar.com Old Status: Open Status: Closed Bug Type: Apache related Operating System: linux 2.2.14 and 2.2.16 PHP Version: 4.0.6 New Comment: The problem solved upgrading Kernel to 2.4.2 (Redhat 7.1). I think that the problem has been caused by the Apache 1.3.20 and the old thread library of the kernels 2.2.14 and 2.2.16. Bye, Denis Previous Comments: ------------------------------------------------------------------------ [2001-07-12 03:18:11] denis@edistar.com Hi to all! I've tried all the new versions of php (from 4.0.4pl1 to 4.0.7pre) and all have given me the same problem: in high traffic situations few apache children crash causing the system to go down. The only way to solve the problem is to power down the machine (no safely reboot command of linux... the console is blocked...). This problem has presented only after 4.0.5 (but 4.0.4pl1 has given problem with Imap). To solve the problem i recompiled apache 1.3.20 with php 4.0.3pl1 and all now is working correctely. The software i used is: - Apache 1.3.20 - Php 4.0.5, 4.0.6, 4.0.7pre The configure line is: ./configure --enable-imap --enable-mysql --with-mysql --with-apache=../$APACHE --with-imap --without-xml --enable-track-vars --enable-memory-limit=yes --with-zlib=/usr --with-gd=/usr/local --with-jpeg-dir=/usr --with-png-dir=/usr --enable-magic-quotes Thank for help, Denis PS: I'm not able to create a gdb backtrace because when i try to attach the gdb to the process, gdb crashes too! ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=12085&edit=1
