$_POST form deletes TextArea 4k (data), but (data) is retained in $_REQUEST

Check your php.ini for post_max_size.

Code:

; Maximum size of POST data that PHP will accept.
post_max_size = 8M

I think it's 8 MB by default, but shared hosting environments often set it lower.
If that doesn't work, check Apache's LimitRequestBody and LimitRequestFieldSize directives.
