Well, I set out tonight to try to gather some info on the blank page issue. After hundreds and hundreds of page loads, I managed to get it to happen twice. I was set up to gather some info including the http headers to see what was going on.
When it happens, the page appears to work, evident by a page source, but nothing displays. So I was thinking something in the headers might give a clue.
And while, not exactly statistically significant, when the two blank pages happend, the exact same thing happened in the http headers – premature termination and on exactly the same place.
So, here is what was the last piece of info in the headers (sorry for the width).

and there was only 4 entries on the generator stats (exact number is likely not important and dependant upon what is in the browser cache), the last one being:
yes, both times it appeared to choke on tiny_mce_gzip.php
so something, and in these two cases it was that file… When a page loads successful, here is what is normal as far as headers in the generator (this was an empty cache):

the point being, there is much more in there AFTER this file that appears to dork up…
also, watching the headers in real time, they always pause on this tinymce file.
also, note the last entry in the header which says
Transfer-Encoding: chunked
on any page that loads successfull, that never appears… and well frankly, chunked sounds bads…
Need to do some research on this, but it “appears” that the blank page issue might be related to tinymce and gzip?
I will try to remember to leave the http headers gathering addon for FF open and see if I can get the same info more than twice.
