Not sure if this is a jetty issue or a logback issue: I'm getting intermittent errors using logback-access to write the jetty access log. Full backtrace below. A race condition? Maybe the socket already closed before the logger gets run? I've seen it on 6.1.24 and 6.1.26 with 0.9.28. java.lang.Error: java.net.SocketException: Socket operation on non-socket at sun.nio.ch.Net.localAddress(Net.java:128) at sun.nio.ch.SocketChannelImpl.localAddress(SocketChannelImpl.java:423) at sun.nio.ch.SocketAdaptor.getLocalAddress(SocketAdaptor.java:147) at java.net.Socket.getLocalSocketAddress(Socket.java:717) at org.mortbay.io.nio.ChannelEndPoint.getLocalPort(ChannelEndPoint.java:341) at org.mortbay.jetty.Request.getLocalPort(Request.java:839) at ch.qos.logback.access.spi.AccessEvent.getLocalPort(AccessEvent.java:445) at ch.qos.logback.access.spi.AccessEvent.prepareForDeferredProcessing(AccessEvent.java:481) at ch.qos.logback.core.OutputStreamAppender.subAppend(OutputStreamAppender.java:211) at ch.qos.logback.core.OutputStreamAppender.append(OutputStreamAppender.java:108) at ch.qos.logback.core.UnsynchronizedAppenderBase.doAppend(UnsynchronizedAppenderBase.java:88) at ch.qos.logback.core.spi.AppenderAttachableImpl.appendLoopOnAppenders(AppenderAttachableImpl.java:64) at ch.qos.logback.access.jetty.RequestLogImpl.log(RequestLogImpl.java:133) at org.mortbay.jetty.handler.RequestLogHandler.handle(RequestLogHandler.java:51) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:765) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:418) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.Server.handle(Server.java:326) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:542) at org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:923) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:547) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:212) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:404) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:409) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:582) Caused by: java.net.SocketException: Socket operation on non-socket at sun.nio.ch.Net.localInetAddress(Native Method) at sun.nio.ch.Net.localAddress(Net.java:125) at sun.nio.ch.SocketChannelImpl.localAddress(SocketChannelImpl.java:423) at sun.nio.ch.SocketAdaptor.getLocalAddress(SocketAdaptor.java:147) at java.net.Socket.getLocalSocketAddress(Socket.java:717) at org.mortbay.io.nio.ChannelEndPoint.getLocalPort(ChannelEndPoint.java:341) at org.mortbay.jetty.Request.getLocalPort(Request.java:839) at ch.qos.logback.access.spi.AccessEvent.getLocalPort(AccessEvent.java:445) at ch.qos.logback.access.spi.AccessEvent.prepareForDeferredProcessing(AccessEvent.java:481) at ch.qos.logback.core.OutputStreamAppender.subAppend(OutputStreamAppender.java:211) at ch.qos.logback.core.OutputStreamAppender.append(OutputStreamAppender.java:108) at ch.qos.logback.core.UnsynchronizedAppenderBase.doAppend(UnsynchronizedAppenderBase.java:88) at ch.qos.logback.core.spi.AppenderAttachableImpl.appendLoopOnAppenders(AppenderAttachableImpl.java:64) at ch.qos.logback.access.jetty.RequestLogImpl.log(RequestLogImpl.java:133) at org.mortbay.jetty.handler.RequestLogHandler.handle(RequestLogHandler.java:51) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:765) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:418) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.Server.handle(Server.java:326) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:542) at org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:923) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:547) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:212) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:404) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:409) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:582)
