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!
Actual result:
