reason of java.net.SocketException: Too many files open in Tomcat, Weblogic or any Java application server is, too many clients connecting and disconnecting frequently at very short

span of time. Since Socket connection internally use TCP protocol, which says that a socket can remain in TIME_WAIT state for some time, even after they are closed. One of the reason to keep closed socket in TIME_WAIT state is to ensure that delayed packets reached to the corresponding socket. Different operating system has java.net.socketexception too many open files websphere different default time to keep sockets in TIME_WAIT state, in Linux it's 60 seconds, while in Windows is 4 minutes. Remember longer the timeout, longer your closed socket will keep file handle, which increase chances of java.net.SocketException: Too many files open exception. This also means, if you are running Tomcat, Weblogic, Websphere or any other web server in windows machine, you are more prone to this error than Linux based systems e.g. Solaris or Ubuntu. By the way this error is same as java.io.IOException: Too many files open exception, which is throw by code from IO package if you try to open a new FileInputStream or any stream pointing to file resource. How to solve java.net.SocketException: Too many files open Now, we know that this error is coming because clients are connecting and disconnecting frequently. If that's seems unusual to your application, you can find the culprit client and prohibit them from reconnecting from making a connection, but if

The application that is running on the JBoss server makes HTTP connections to other systems using Apache HTTPClient and the code is releasing the connections using the HTTPClient.can somebody pls help with this issue.JBoss 4.2.2 GA, RHELinux -- Quad Code 8GBRAM,There has been some internal JBoss errors which started occurring at a rapid pace and the server.log went up from 900kb to 350mb in a span of 30-60mins.
