I have imported the IP-Banlist from http://www.stopforumspam.com/downloads/ (All IPs as CSV). After that, when i call the page ip-banlist, i get the described error. The list contains more then 33700 IPs. The SQL-Statemnet on /includes/acp/acp_ban.php selected all stored records, so the error pops up. Affected is the change-textbox.

I've wrote a small fix, that build a side pagination for the textbox, if more then 1000 records where counted. If you like, i attched it. All changes are marked with "Bussibaer: Spam-Addon". On the html file i add the rows 94 to 98 and change the closing < / dd > tag
