Plugin – Comment Timeout

I have been using the comment timeout plugin for about 8 months with no problems, but today when I tried to click on one of my categories I received this message:

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 35 bytes) in /var/www/html/news/wp-content/plugins/comment-timeout/comment-timeout.php on line 228

Now I use this plugin for all of my categories and the rest all work fine. All of my categories use the same category.php file so that is not the problem. When I deactive the plugin everything works fine. Any help would be greatly appreciated.
