Not specifically, but as Russ and Cameron have mentioned, there is a limit to the number of threads that can run. And running serial HTTP requests is going to be sloooooow. You could increase the thread count, then use CFTHREAD to run some of these concurrently if you really need to be doing them at serve time. > Is there a way I can see the total number of outbound http calls going on? I'm not aware of anything in CF that would specifically let you see the number of outbound HTTP requests, but you could certainly see what scripts are being executed by what threads, so if you had a concurrent CFTHREAD approach, you could get a pretty accurate count. You could monitor network connections outside of CF to see how many outbound HTTP requests the machine is making, of course. > It would seem to me that this is a poor design under load conditions.

Yes, you should ideally do it either before (via caching) or after (via asynchronous processing) the user wants this content, instead of exactly when the user wants it.
