mysql_pconnect(): send of 5 bytes failed with errno=32 Broken pipe.

Question

I've been using the same DB abstraction library for years. But today it started writing these Notice (8) messages in my log.

The application is working correctly but every time a script connects to the DB the same notice is logged.

I cannot think what might have changed. This is happening on my local dev machine.

OS X 10.6.2
PHP 5.3.0 (cli) 
mysql Ver 14.12 Distrib 5.0.87
mysqlnd 5.0.5-dev - 081106 - $Revision: 1.3.2.27 $

Answer 1

If you really want to investigate the matter take a look at http://blog.ulf-wendel.de/?p=159
It explains how you can create trace files for the mysqlnd activites.
