Default behavior wwhen Timeout Requests not checked?

[Wally Randall]

In looking at our CF 8 production WEB servers I found one that does not have the Timeout Requests after nn seconds checked in the administrator.

What is the impact of this?  Everyone discussing this subject advises having it set but what is the impact of it being disabled?  I find no documentation on the default behavior that CF takes when Timeout Requests is not enabled.

I'm pretty sure that requests simply won't time out in that case.

Just to add to Dave's comment...

The only problem you might run into is that since the requests simply do not time out, that means if there are any really long running requests and many requests of that same type (long running), it will tie up your server's thread pool causing other requests to have to wait before they are handled.  The server then appears to be very slow and unresponsive. 

Whereas, if a timeout is set, then the long running requests will timeout preventing a situation where the server is saturated by long running requests inhibiting other requests.  However, simply setting a timeout is not the immediate right solution to the case of long requests bogging the server because the consequence is the long running requests will be timed out which might not be acceptable to the usability of the site.  

However, if you do not have any long running requests, then your server may not run into this problem.
