I don't recognize that 'unknown host' log entry. If the transfers wait for whatever is writing it, it might cause a delay where the time will depend on the DNS response - if you get an immediate NXDOMAIN from a local server it should be quick but if you are referred to an upstream and possibly firewalled server that won't respond you would have a multiple-second wait for a timeout. You could test the theory with "nslookup 172.17.0.1" to see how long the response takes if that is the actual address. -- Les Mikesell lesmikes...@gmail.com ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
