Hi We are facing a repeating problem running JBoss App 4.2.2 GA (Jdk 1.6_02) on Red Hat linux. We are getting the following exception: 2008-09-15 07:49:08,684 ERROR [org.apache.tomcat.util.net.JIoEndpoint] Socket accept failed | java.net.SocketException: Too many open files | at java.net.PlainSocketImpl.socketAccept(Native Method) | at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:384) | at java.net.ServerSocket.implAccept(ServerSocket.java:453) | at java.net.ServerSocket.accept(ServerSocket.java:421) | at org.apache.tomcat.util.net.DefaultServerSocketFactory.acceptSocket(DefaultServerSocketFactory.java:61) | at org.apache.tomcat.util.net.JIoEndpoint$Acceptor.run(JIoEndpoint.java:309) | at java.lang.Thread.run(Thread.java:619) | | This did not happen on Jboss 4.0.2. i've tried looking for some answers in the forum but did not find any final conclusions or any solution that solves our problem. can anyone advice? forums ref: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4131756#... https://jira.jboss.org/jira/browse/JBAS-5570 http://www.jboss.com/index.html?module=bb&op=viewtopic&t=72154 http://www.seamframework.org/Community/TooManyOpenFilesJeopardizingSeamAp...
