Issues with long SQL inserts

Server is running PHP 4.1.2, APC 1.1.0pl1, MySQL 3.23.47, Apache 1.3.23 on a built-from-scratch Linux system with kernel 2.4.17, glibc 2.2.5, and gcc 3.0.4. I'm using a fairly simple script to take input from a form, and add it to a database. The database has the following structure: ID - mediumint(8), primary key, auto_increment Added - date Modified - timestamp(8) Title - varchar(60) Text - text What's happening is whenever I try to add an article that has text with a size of over around 9 KB, the browser never finishes loading, and the article doesn't appear in the list. When I hit the stop button on the browser, the article will then appear in the article list, but incomplete - it is always cut off at the same spot. This sounds like some kind of buffer issue, but I've looked through all of the applicable settings that I could find in both my PHP and MySQL configuration files, and have found nothing. Any ideas? Thanks in advance. To see the source code for this script, go to http://test.mvpsoft.com/add.txt . Thanks in advance for any help!
