Thread:Project:Support desk/Apache bus error on mediawiki sign in

Apologies if this is not a mediawiki problem, but it is only on mediawiki sign in thaty I am getting this.

Platform: Solaris 10 Generic_141414-01

Web Server: Apache httpd v 2.2.17 (prefork)

PHP: v5.3.5

PHP Configure command line:'./configure' '--with-apxs2=/usr/local/httpd-2.2.17/bin/apxs' '--with-openssl' '--with-zlib' '--with-jpeg-dir=/usr/local' '--with-gdbm' '--with-db4' '--with-png-dir=/usr/local' '--with-xpm-dir=/usr/local' '--with-freetype-dir=/usr/local' '--with-t1lib' '--with-gettext' '--with-iconv' '--with-gd' '--enable-ftp' '--with-mysql=/usr/local/mysql' '--with-readline' '--enable-soap'

Mediawiki: v1.16.2

MySQL: v5.1.46

When a user of our internal media wiki forgets their password and clocks on the 'email me my password' button, the username/passwor dcombo becomes unusuable. New registrations seem fine.

When a user tries to use the email password, then goto the login form, fill in the the form and clicks login they just get a blank page. This is because, under the hood, the apache child process has bus errored.

Example line from apache error log: [Thu Feb 17 11:56:46 2011] [notice] child pid 4084 exit signal Bus error (10)

I am assuming this is a php problem, possibly because of any underlying library., but it is strange that it only happens on mediawiki sign in.
