I'm running PHP 5.3.6, Mysql 5.1.51 and Apache 2.2.17 I have code that does a simple mysql_query(); the query on the commandline returns an empty set. when run via PHP and the web server, the page hangs, it never gets to the if (mysql_num_rows($result) > 0) {}. and the queries per second on mysql goes from roughly 4 per second to about 12,000. Does anyone have any ideas? Thanks, Curtis
