Re: Help! Apache 2.2 gives segmentation fault errors with PHP.

Hi all, Yesterday I had trouble when configuring Apache 2.2 with PHP 4.4.2, which caused Apache to crash (segmentation fault) when calling various PHP functions. Just before heading home I encountered the source of the issue, as well as the solution. The hint to the answer resided in the /var/log/httpd-error.log file:

And the /var/log/httpd-error.log file mentions the following (at the end):

[...] PHP Warning: Function registration failed - duplicate name - bzopen in Unknown on line 0 PHP Warning: Function registration failed - duplicate name - bzread in Unknown on line 0 [...] ..............many more similar messages...............

This obviously hinted at these functions (i.e php4-extensions) somehow being doubly present and called. Issuing a 'pkg_info | grep php' command was most illustrative, and showed over a screen full of output like this: mod_php4-4.4.2_1,1 PHP Apache Module php4-bcmath-4.4.2_1 The bcmath shared extension for php

php4-bz2-4.3.10     The bz2 shared extension for php
php4-bz2-4.4.2_1    The bz2 shared extension for php

php4-calendar-4.4.2_1 The calendar shared extension for php php4-crack-4.4.2_1 The crack shared extension for php php4-ctype-4.4.2_1 The ctype shared extension for php

php4-dio-4.4.2_1    The dio shared extension for php

php4-domxml-4.4.2_1 The domxml shared extension for php php4-exif-4.4.2_1 The exif shared extension for php php4-extensions-1.0 A "meta-port" to install PHP extensions

php4-gd-4.3.10      The gd shared extension for php
php4-gd-4.4.2_1     The gd shared extension for php

[...more lines where those came from...] Tadaaaah!! there we go: indeed several extensions were somehow not removed properly when a previous upgrade to PHP 4.4.2 (from v4.3.10) was performed! As to the reason for this, go figure, I always install from the ports by doing a 'make' 'make deinstall' 'make reinstall' sequence when upgrading... Anyway, manually removing all PHP extensions using the various individual 'make deinstall' sequences (and bluntly pkg_delete for pear). Then, I cleanly redid the process for installing mod_php4 and the extensions, and now all is working fine! Tnx for thinking along with me, and beware of this potential pitfall! :) Cheers! Olafo
