[SOLVED] Upload Error at 3MB, but none at 1MB

[urtlking2jo]

I am using a java applet to upload files images and pdf files into a mysql database.  Everything up to 1MB seems to work fine, but I need to be able to upload pdf files up to about 3MBs. I keep getting the error "Warning: fread(): supplied argument is not a valid stream resource in - [upload handler php]".  From searching on the web, I found that it could be a mysql issue due to packet size limitations, but I changed my max_allowed_packet to 16M and the error continues.  The server is quick, and the upload is taking under 1 minute, so I don't think anything should be timing out that quickly.  Any ideas?
