Re: Possible time out
Is the form re-submitting each time you check a box? I bet it's the post parameter limit thing. The behavior you're describing (white screen) is exactly what happens when you hit that post param limit.

Re: Possible time out - Not
Hi Matthew and Anthony It was the post param limit issue There were lots of hidden input variables associated with the check box. Bummer just getting a white screen without any error message.

Re: Possible time out
I find that it bites me every time I do a CF9 install (for instance, after rebuilding my dev laptop). So it happened in the last month or so to me, which is the only reason I even remember the cause ;). Though WHY there's no error output to the screen is highly annoying. -- Matthew Williams Geodesic GraFX ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:357684 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Possible time out
Hi Folks Running CF9 developer I have a form with 24 items and check boxes. When over 13 check boxes are checked the screen just goes white, no error message is displayed, nor is the CF debug info shown. Each check box initiates Database queries. Total time on the template is 2449 ms when 12 boxes are checked. The timeout request in CF is not checked. I don't have any problems on the production server with exact same template. Any ideas?

Re: Possible time out
To check your theory, try setting the timeout to a large number and see if the problem goes away.Then you know for sure what is causing the problem. There are a number of things you can do to reduce the impact of a long processing time: [A] look for ways to reduce the processing time.I dont know what you're doing so I can't be specific about what you could do but maybe combine some of those checkbox results so you have only one query between them. Or cache some of the queries so they come back faster from the database. [B] If you can't speed up the processing time, look for ways to reduce the effect. For example use threading (CFTHREAD tag) to run simultaneous queries and start displaying the result even though not all the queries have processed yet.You can use force coldfusion to display the incomplete page if you use CFFLUSH tags to output the page up to that point, even though the page processing isnt complete yet. Often, even though you can't speed up the page process, you can give the user the appearance of a faster page process by displaying parts of the page while processing still continues. [C] Use both A and B above.

Probably I've just told you something you already know, and if so, I'm sorry. If you give us more details or maybe some code to look at, no doubt we can think of other things you can do too.
