I think that the ClientTimeOut setting is supposed to be for idle time on the network connection, but under some circumstances it isn't reset on activity and becomes the total timeout for the run. Try bumping it much higher, especially if your current setting is approximately the time when a timeout occurs. Also rsync can have long periods of idle time reading blocks where there are no differences from the comparison base. If the connection goes through a NAT gateway or a stateful firewall, the devices may time the connection out and be blocked. If you are running over ssh, you can enable keepalives on the ssh connection with the ServerAliveInterval option. Standalone rsync may also have a way to enable keepalives but I don't know where to set it. -- Les Mikesell lesmikes...@gmail.com ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
