10x more traffic? Yeah that will hit you where it hurts for sure. The first advise I would give is to look at changing you code to use the Google hosted version of these libraries: http://encosia.com/3-reasons-why-you-should-let-google-host-jquery-for-you/ > Also, the rich format of the new website is taxing the ColdFusion > engine. > Yes, 10x traffic will do that. :) > When the website seems to stop, the number of connections to CF's port > 51011 increase from about 5 (average normal) to about 500. > This smells like CF is getting hung and IIS continues to send it requests. This leads to a dogpile effect on CF where it's still receiving new requests from IIS but can no longer respond. This is usually due to a problem with something getting hung up in your CF code, or with SQL. For example, a SQL call that never comes back from the database, or some CFHTTP calls that never hear back from their servers, or a CFLOCK tag that's in a deadlock. If this is in fact the problem - the best way to troubleshoot this is install something like FusionReactor on the server and get a stack trace while the error is occurring. This will quite literally give you the exact line of ColdFusion code causing the problem. I'd bet a dollar that it's one of the three things I mentioned above. -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:352150 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
