If you aren't familiar with CFLOCK, check the documentation. You could also reduce the number of threads as Russ suggests, however I would recommend putting some code in place to do something when that max is reached or else you're just creating a new problem from the old one. > Is there a way I can see the total number of outbound http calls going on? > Outside of CF there would be a number of network monitoring tools you could use for this.

Try loading the content using a background process of some sort (ie: scheduled task) and then staging it all in a table. That way when the user requests the page you aren't triggering a bunch of CFHTTP calls. -Cameron -- Cameron Childress -- p: 678.637.5072 im: cameroncf facebook <http://www.facebook.com/cameroncf> | twitter<http://twitter.com/cameronc> | google+ <https://profiles.google.com/u/0/117829379451708140985> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| 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:353234 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
