PHP Bug Type: PDO related
Bug description: PDO fails for no apparent reason, pages that works randomly
breaks
Description:
------------
I run an Apache (2.0.58) server, PDO (1.0RC2) and APC (3.0.11).
My PDO randomly gives me this error (Fatal error: Call to a member
function execute() on a non-object in
/var/www/*/htdocs/classes/pdoMysql.class.php on line 33
), without any errors in the log.
The error occurs more frequently when the server is loading, but it also
happens with no particular load, and some seconds after it works flawless
again.
I've tried the latest CVS snapshop for PHP 5, but it didn't fix the
problem.
