Thank you for your bug report and for your troubleshooting work. NOTE: I am not a developer or even a bug triager, I am just some guy. But still, I suspect this is not a MediaWiki bug. If you could please provide us with more information: 1. What is your: - Apache version - PHP version - Operating system and version 2. How often has this segfault happened? 3. Have you done anything with your /wiki/ directory since the crash happened, or do you still have the directory? 4. Did you get any weird messages during the installation?
Check also for presence of various PHP or Zend extensions. Some may have compatibility or stability issues.
Jason, Brion - thanks for the shout, and here's the add'l info. 1. Apache 2.2.4 PHP 5.2.1 REHL (2.6.9-34.EL) on a dell x86 eAccellerator 0.9.5 2. every request to the mediawiki = seg fault. Other PHP apps running fine 3. I installed into /mediawiki - directory untouched except for removal of /config 4. Not weird errors - install was point-click and done. php.ini section: extension="eaccelerator.so" eaccelerator.shm_size="50" eaccelerator.cache_dir="/tmp/eaccelerator" eaccelerator.enable="1" eaccelerator.optimizer="1" eaccelerator.check_mtime="1" eaccelerator.debug="0" eaccelerator.filter="" eaccelerator.shm_max="0" eaccelerator.shm_ttl="0" eaccelerator.shm_prune_period="0" eaccelerator.allowed_admin_path = "/usr/local/apache2/htdocs/eacc.php" php config './configure' '--with-apxs2=/usr/local/apache2/bin/apxs' '--disable-cli' '--disable-cgi' '--with-config-file-path=/etc' '--with-zlib' '--enable-calendar' '--with-curl' '--enable-exif' '--enable-ftp' '--with-gd' '--enable-mbstring' '--enable-zip' '--enable-zend-multibyte' '--with-magickwand=/usr' '--with-mysql' '--with-mysql-libs=/usr/lib/mysql' '--with-mysql-headers=/usr/include/mysql' '--enable-soap' eAccel config ./configure --with-eaccelerator-disassembler --with-eaccelerator-info --enab le-eaccelerator=shared --with-php-config=/usr/local/bin/php-config apache config ./configure --enable-modules=most --enable-mods-shared=all --enable-so
eAccelerator 0.9.5 has multiple known problems with PHP 5.2.x... try removing that. You may have to build 0.9.6 prereleases from source control, or try APC or another alternative.
remove eAccel 0.9.5 and use APC (latest) issue resolved - not a MediaWiki issue
