uhmm? anyone? Previous Comments: ------------------------------------------------------------------------ [2004-05-06 13:44:11] noam at kaktos dot co dot il Description: ------------ We use Apache2 with Worker MPM here. PHP's children die all the time: [Thu May 06 14:39:24 2004] [notice] child pid 30028 exit signal Segmentation fault (11) [Thu May 06 14:39:27 2004] [notice] child pid 30094 exit signal Segmentation fault (11) [Thu May 06 14:39:29 2004] [notice] child pid 30158 exit signal Segmentation fault (11) [Thu May 06 14:39:31 2004] [notice] child pid 30222 exit signal Segmentation fault (11) [Thu May 06 14:39:33 2004] [notice] child pid 30286 exit signal Segmentation fault (11) etc. My configure line: './configure' '--with-pear' '--enable-experimental-zts' '--with-mysql' '--with-mysql-socket=/tmp/mysql.sock' '--disable-ipv6' '--enable-safe-mode' '--with-apxs2=/usr/local/apache/bin/apxs' '--with-imap=/usr/local/imap-2002e' '--with-gettext' '--with-xml' '--with-dom' '--with-zlib-dir=/usr' Nothing unique here. The diff between php.ini-dist and my php.ini below: http://www.kaktos.co.il/~noam/php.ini-diff I backtraced using your guidelines and it all leaded to php's _db_return_ function in the mysql extension. The code involved: #ifndef THREAD if (state->framep != NULL) state->framep = (char **) *state->framep; #endif I concluded that PHP scripts who use MySQL, crash. I tried to figure out the code, I couldn't. Strangely enough, if I commented it out every worked charmly. I hope I helped --noam P.S.: I've also tried the CVS version: php4-STABLE-200405061030, with same results. Thank you for your patience and this fine product!
