I have a VERY simple statement, that I am sure is returning results, but it's crashing Apache... it works fine on my dev box (Windows Vista running Xampp), but it crashes my demo box (running CentOS 4, Apache 2)...

SELECT * FROM tablea WHERE field1=<num> AND field2=<num>

That's it...

$stmt = $db->query($query);
$rows = $stmt->fetchAll();

It crashes on the "$stmt = $db->query($query);" line, every time.
