CF server cause blank pages?

[riluve]

After development on this web app/ site for a month or more, yesturday, out of the blue, I started to get starnge results, my *.cfm pages were coming up BLANK!

Actually, I thought it was some programming error in my code and I was trouble shooting it, when I noticed on a near by computer (as an FF/IE client) the same page was loading fine.

To be clear, on the machine I was working on, pages loaded blank in both IE & FF - while on another machine they loaded fine.

I noticed then I could clear the problem by closing IE or FF when they reached a "saturation" point of some type and started fetching blank pages.

At first I thought then it was an issue with my development machine, however, I went home and continued to work from there and noticed the same issue crop up eventually.

The only common thing between these two machines is the CF server (and the apache server) both of which have worked flawlessly for the past two years (until Wednesday).

It seems to me a new web page I was working on is somehow saturating the CF environment but not producing any error messages - just serving up blank pages.

So does anyone have any clues or ideas about this type of issue? Maybe a few hints to a solution?

While I agree that may work in the short term, I am looking for a long-term actual fix to the problem.

Thank you though.

and the actual problem is... ?

My cfm pages/server are causing browsers to load blank pages and not generating an error.


The source of the problem is limited to one website (with heavy cfm/query code) but the effect happens rapidly on more than one client browser on more than one client machine running under -fresh- installations of windows (1 week old) and on freshly booted machines.

post the url of that one website and let us have a look

Well, I will consider posting the link when I have finished debugging the code and turn my debug data dump off.

However, I can't imagine how seeing it would actually help. CF simply sends a blank page - not a single stitch of HTML inside, so what you would see is perfectly generated CF HTML until you reload the page a few times and bamm - the HTML is gone.

The browser thinks the transaction was complete. There is no real browser or webserver issues involved.

In fact, I tried clearing the cache and it had no effect. To clear the issue, you must close the browser and reopen it.

From what I understand that should also kill any active session and start a new session - so i am suspicious that i am crowding out my servers session space, but there is no real indication there is a problem even in the server logs.

Just blank CFM's with no indication why.

oh



well, i'm not going to be able to help, sorry, i think that scenario is a bit beyond my skill set

can you not post your code? you are not likely 'crowding session space', if you were you would run out of memory and get a specific Java error. Also, a session timeout will not be cleared by simply closing the browser, clearing cookies will kill your session. Are you using any cfheader, cfcontent or cfflush tags on this page? Have you narrowed it down to any specific page that is causing the issue?
