ID: 53287 Comment by: bryan at esited dot com Reported by: bryan dot tong at gigenet dot com Summary: PDO 5 Byte write to a broken pipe when forked Status: Not a bug Type: Bug Package: PDO related Operating System: CentOS 5.5 x86-64 PHP Version: 5.3SVN-2010-11-10 (snap) Assigned To: mysql Block user comment: N Private report: N New Comment: Hello, I wanted to note that a common mysql configuration error will cause this issue. Try changing the following. wait_timeout=60 to wait_timeout=3600 This is located in the /etc/mysql/my.cnf Basically the wait_timeout value should equal that of client_max_read_timeout in NGINX. Hopefully this will help someone else correct the issue. Thanks Previous Comments: ------------------------------------------------------------------------ [2012-03-06 01:17:11] johan...@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php ------------------------------------------------------------------------ [2011-01-31 10:42:56] bryan dot tong at gigenet dot com Though it can really make parsing the output a pain when there are multiple versions of mysqlnd floating about. ------------------------------------------------------------------------ [2011-01-31 10:27:42] u...@php.net This does not smell like an error rather more like mysqlnd being more verbose. No bug, a feature, I'd say. ------------------------------------------------------------------------ [2010-12-05 21:23:46] seza at paradoxal dot org I have the same error message with php.5.3.3 (send of 5 bytes failed with errno=32 Broken pipe) but in a different context more simply to reproduce : I have a simple website (no fork or stuff like that). It make persistent connection with pdo to mysql (mysqlnd). The errors are raised when the mysql is server is restarted. When mysql server is off error message are mysql server is gone away. No problem with that but once the mysql server is restarted and during 15 minutes I have sometimes this error message (send of 5 bytes failed with errno=32 Broken pipe). Certainly a reuse of a cached connection to mysql before it was restarted. PS : I use mysql_sock connection (mysql:unix_socket=/var/run/mysqld/mysqld.sock) ------------------------------------------------------------------------ [2010-11-26 13:19:45] johan...@php.net The description mentions forking, the sample code not. Please provide a complete script showing the issue. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
