title: mysql_pconnect(): send of 5 bytes failed with errno=32 Broken pipe
body: <p>I've been using the same DB abstraction library for years. But today it started writing these Notice (8) messages in my log.</p>
  
  <p>The application is working correctly but every time a script connects to the DB the same notice is logged.</p>
  
  <p>I cannot think what might have changed. This is happening on my local dev machine.</p>
