ezSQL has troubles handling large tables?

Hi there,

I noticed a problem trying to SELECT * FROM some table with 14000 rows.

I just use:

$db->get_results("SELECT * FROM archives");
echo $db->num_rows;

and nothing. Really blank page, no errors, messages, etc, even after $db->debug();

I use php 4.4.2 and mysql 4.1.18

It's all all right when I use regular php functions like mysql_connect + mysql_query and mysql_num_rows...without ezSQL.

Please help,
Peter
