"Nessus scan makes JBoss 5.1.0.GA stop processing web requests" To view the discussion, visit: http://community.jboss.org/message/548382#548382 -------------------------------------------------------------- We are seeing a similar issue, but it is not caused by a scanning application. On the web server side we see occasionally see threads with this stack: 75: [Thread[jrpp-1390,5,jrpp]]/id=49440/hc=13398717/shc=*/state=RUNNABLE/name=* java.net.SocketInputStream.socketRead0(Native Method) java.net.SocketInputStream.read(SocketInputStream.java:129) java.io.BufferedInputStream.fill(BufferedInputStream.java:218) java.io.BufferedInputStream.read(BufferedInputStream.java:237) java.io.ObjectInputStream$PeekInputStream.peek(ObjectInputStream.java:2249) java.io.ObjectInputStream$BlockDataInputStream.readBlockHeader(ObjectInputStream.java:2429) java.io.ObjectInputStream$BlockDataInputStream.refill(ObjectInputStream.java:2499) java.io.ObjectInputStream$BlockDataInputStream.read(ObjectInputStream.java:2571) java.io.ObjectInputStream.read(ObjectInputStream.java:820) org.jboss.remoting.transport.socket.MicroSocketClientInvoker.*readVersion*(MicroSocketClientInvoker.java:1263) org.jboss.remoting.transport.socket.MicroSocketClientInvoker.transport(MicroSocketClientInvoker.java:838) org.jboss.remoting.MicroRemoteClientInvoker.invoke(MicroRemoteClientInvoker.java:165) org.jboss.remoting.Client.invoke(Client.java:1724) org.jboss.remoting.Client.invoke(Client.java:629) org.jboss.aspects.remoting.InvokeRemoteInterceptor.invoke(InvokeRemoteInterceptor.java:60) org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) org.jboss.aspects.tx.ClientTxPropagationInterceptor.invoke(ClientTxPropagationInterceptor.java:61) org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) org.jboss.ejb3.security.client.SecurityClientInterceptor.invoke(SecurityClientInterceptor.java:65) org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) org.jboss.ejb3.remoting.IsLocalInterceptor.invoke(IsLocalInterceptor.java:74) org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) org.jboss.aspects.remoting.PojiProxy.invoke(PojiProxy.java:62) $Proxy5.invoke(Unknown Source) org.jboss.ejb3.proxy.impl.handler.session.SessionProxyInvocationHandlerBase.invoke(SessionProxyInvocationHandlerBase.java:207) org.jboss.ejb3.proxy.impl.handler.session.SessionProxyInvocationHandlerBase.invoke(SessionProxyInvocationHandlerBase.java:164) $Proxy1643.completeMyOrder(Unknown Source) On the jboss server for each thread above we usually see at least 2 jboss threads with the following stack: 816: [WorkerThread#10[10.1.4.245:46454]]/id=6923/hc=1806701791/shc=*/state=RUNNABLE/name=* java.net.SocketInputStream.socketRead0(Native Method) java.net.SocketInputStream.read(SocketInputStream.java:129) java.io.BufferedInputStream.fill(BufferedInputStream.java:218) java.io.BufferedInputStream.read(BufferedInputStream.java:237) java.io.ObjectInputStream$PeekInputStream.peek(ObjectInputStream.java:2249) java.io.ObjectInputStream$BlockDataInputStream.readBlockHeader(ObjectInputStream.java:2429) java.io.ObjectInputStream$BlockDataInputStream.refill(ObjectInputStream.java:2499) java.io.ObjectInputStream$BlockDataInputStream.read(ObjectInputStream.java:2571) java.io.ObjectInputStream.read(ObjectInputStream.java:820) org.jboss.remoting.transport.socket.ServerThread.*readVersion*(ServerThread.java:1038) org.jboss.remoting.transport.socket.ServerThread.processInvocation(ServerThread.java:673) org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:551) org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:232) I am not sure what is going on, but it looks like there is something that occasionally gets messed up with these "readVersion(...)" methods. These threads will hang for hours and days. The only way we can get these to stop hanging is to send a Thread.interrupt() to the threads on the web server side. Sending the interrupt to the thread on the jboss side only moves the problem to a different thread and doesn't stop the web server threads from hanging. We are not sure what is causing this, but it appears to be a bug in jboss. We are using 5.1.0 GA as well. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/548382#548382] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2075]
