Operating system: FreeBSD 4.6
PHP version: 4.2.3
PHP Bug Type: Sockets related
Bug description: Segmentation Fault
Afternoon:
I'm having problems with PHP CGI crashing and I have no idea why. The
script I'm running hasn't changed, nor has the server setup. It ran fine
for several weeks and then started crashing. I rebooted the server and it
was fine for a couple of days... now its crashing again.
The script is a daemon that listens on a port for incoming XML fragments
(you can see pieces of this XML at the end of the backtrace) - so this
could be Socket or XML related.
I was running PHP 4.2.1. I upgraded to 4.2.3 and its still doing it. I
have also upgraded to the latest snapshot and ran this through PHP
4.3.0-cli - same result.
./configure --with-mysql --enable-debug --enable-shared=yes
--without-apache --enable-ftp --with-mcrypt --with-curl --enable-sockets
Here is a backtrace, but its all greek to me. Can anyone explain what on
earth all this means?
