Edit report at https://bugs.php.net/bug.php?id=51091&edit=1 ID: 51091 Comment by: ryan dot pendergast at gmail dot com Reported by: achristianson at yakabod dot com Summary: Persistent PDO Connections Crash Status: Closed Type: Bug Package: Reproducible crash Operating System: CentOS 5.4 PHP Version: 5.3.1 Assigned To: dmitry Block user comment: N Private report: N New Comment: I run php5-fpm (php v 5.3.3) on 32bit ubuntu 10.10 and am seeing the same issue - even when disabling garbage collection. It seems as if fpm is not obeying the disabling of garbage collection. I'm using mysql_pconnect().. /usr/sbin/php5-fpm -i | grep -i zend.enable_gc zend.enable_gc => Off => Off Still produces (Here is my backtrace): Core was generated by `/usr/sbin/php5-fpm --fpm-config /etc/php5/fpm/main.conf'.

Some backtraces in: https://github.com/midgardproject/midgard-php5/issues/50 ------------------------------------------------------------------------ [2010-12-27 23:05:29] lsmith@php.net I should add that I have only seen this issue when running my entire test suite on the CLI. Running the crashing unit tests individually makes the issue go away. ------------------------------------------------------------------------ [2010-12-27 23:03:57] lsmith@php.net I am also seeing segfaults/bus errors, which go away after disabling GC on PHP 5.3.4 using PostgreSQL via Doctrine 2.0. Though the issues only appeared when I added ext intl. I am seeing these issues on OSX and Debian. ------------------------------------------------------------------------ [2010-10-12 00:50:57] felipe@php.net I can't reproduce this as well. (probably already fixed...) ------------------------------------------------------------------------ [2010-09-10 00:01:21] matth+php at mlalonde dot net For the record, we are using Doctrine 2.0 (which uses the PDO) and PostgreSQL. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
