Description:
------------
On of my co-worker experienced, that some of the mysql_pconnect calls are 
returning this error.
The exact same symptoms are described in the manual:
http://php.net/manual/en/function.mysql-pconnect.php#99380
the code which produce this was working fine before migrating to 5.3

Test script:
---------------
<?php
mysql_pconnect();

Expected result:
----------------
successful connection every time

Actual result:
--------------
sometimes we get the PHP warning, and we had to retry the connection

Afair, we already have some checking code in the common connector function for ext/mysql to check for "server has gone away" when attempting to re-use a persistent connection. But it is hard to reproduce if the result isn't consistent.

I tried to reproduce it a few times, but without luck. Any specific MySQL Server versions, or other data that could provide useful?

No solution? I'm using PHP 5.3.8.
