Emacs stops > changing the color (global-font-lock-mode) of comments after certain point > ( 100 lines or so) after that it shows the comments as normal text and > highlights the keywords such as "do" "for" etc.. My crystal ball says that you have an open-paren or open-bracket or open-brace in column 0 somewhere inside your 150-lines-long comment. Emacs thinks this indicates a "beginning of defun" and thus assumes it's not inside a comment. This heuristic is used in some cases but not all the time, so the highlighting will sometimes be correct and sometimes not depending on where the font-locking has started (since you're presumably using jit-lock which highlights the buffer on the fly in small increments).
