Greetings: It turns out that technically speaking CF doesn't cache the DNS, but the JVM does. In this case the JVM DNS cache was corrupted and we were being directed to the wrong ip. We set the time to live parameter in the JVM DNS cache to something other than "forever" and restarted the server. This fixed the problem. This one was very interesting and challenging.

Yes, that's so. And while there doesn't seem to be a way to clear it (other than to restart CF), there is a way to control how long it's set to live. For more, see these blog entries (one really old, one relatively old): http://tjordahl.blogspot.com/2004/10/cfmx-and-dns-caching.html http://coldfused.blogspot.com/2008/01/dns-lookup-caching-in-coldfusionjava.html And the following more generic resources: http://docs.oracle.com/javase/6/docs/technotes/guides/net/properties.html#nct http://www.rgagnon.com/javadetails/java-0445.html http://serverfault.com/questions/459814/clearing-tomcats-dns-cache Hope that helps. /charlie From: ad...@acfug.org<mailto:ad...@acfug.org> [mailto:ad...@acfug.org] On Behalf Of Wilson, Brooks Sent: Thursday, May 16, 2013 10:20 AM To: discussion@acfug.org<mailto:discussion@acfug.org> Subject: [ACFUG Discuss] Getting Connection Refused Greetings: I'm using a CFFEED tag to retrieve an RSS feed. It has suddenly stopped working. Nothing has changed. When we trace the request - nothing happens. I was reading the CF caches DNS entries - but I don't see any information on how to clear the cache. Does anyone have any experience with misbehaving CFFEED/CFHTTP tags?
