Comment form hangs?

Hello–

I am using WP 1.2.2, MySQL MySQL 4.1.7, and PHP 4.3.9 (details: http://karchner.com/blog/info.php ) on FreeBSD 4.8

WordPress “sticks” when a new comment is entered, never returning a results page or an error, it just never downloads.

Feel free to test it here:

Any ideas?
