Just like the subject states, Im having trouble submitting lengthy text into a form. Im on a VPS and my post_max_size = 8m and my upload_max_filesize = 2m, which should be able to handle the lengthy text. The text I'm trying to submit is about 5 paragraphs. I have another site on a shared server with the same settings and I have no problems. It's only the VPS giving me a headache. Please help. Thanks!

Your settings are fine.

It doesnt work only for long text or for few words too?

If you are submitting them via a GET request, try with a POST.

I believe the total size of an url, so in a GET request, can be limited, and if the value is too big, it could invalidate the submit.

Tripy it can't be because he's using the $_GET method because it did work on another server. What exactly happens when you try to submit the text? 5 paragraphs isn't 'lengthy'. Have you ever been to submit text that long on any other forms on your VPS server? The script you're using might help. What happens to the text after you submit it? What versions of PHP do both servers run (not required)? After you answer these questions I'm pretty sure I can figure it out.
