To my understanding Tomcat uses separate DNS-cache on linux. How can I clear it ?
Our tomcat server is running an app that uses service on another server that got it's IP-address changed. Now I am getting noRouteToHost-exceptions even when the service on the another server seems to be accessible using it's dns-name when testing from another computer. Also when pinging the the "new-ip"-server from the server that got tomcat installed using its DNS-name the ping pings the correct new IP-address.
