Is there a limit on the amount of content that can be entered into a rich text field?

Is there a limit on the amount of content that can be entered into a rich text field?

I'm pasting documentation into my RTE field and when I go to view them again they are clipped at roughly the same point in the document (the 304th - 318th line). I need there to be able to paste content into these fields without a limitation.
