A curious error in our model (see code below). Scenario I am logged in as account 'man1' in the model. Everything is working fine. When I log out and try to log in again as MxAdmin the model seems to freeze. The log gives the stacktrace below. I can't pinpoint what the problem is. Also, I get the following messages in the console after the error occurred when continuously trying to login as MxAdmin: It seems that the model still thinks that I'm account man1 instead of MxAdmin. org.eclipse.jetty.io.EofException at org.eclipse.jetty.http.HttpGenerator.flushBuffer(HttpGenerator.java:952) at org.eclipse.jetty.http.AbstractGenerator.blockForOutput(AbstractGenerator.java:518) at org.eclipse.jetty.server.HttpOutput.write(HttpOutput.java:182) at org.eclipse.jetty.server.HttpOutput.write(HttpOutput.java:101) at org.apache.commons.io.IOUtils.copyLarge(IOUtils.java:1720) at org.apache.commons.io.IOUtils.copyLarge(IOUtils.java:1696) at org.apache.commons.io.IOUtils.copy(IOUtils.java:1671) at com.mendix.externalinterface.connector.ResourceRequestHandler.processRequest(ResourceRequestHandler.java:70) at com.mendix.externalinterface.connector.MxRuntimeConnector.processRequest(MxRuntimeConnector.java:63) at com.mendix.core.MxRuntime.processRequest(MxRuntime.java:916) at com.mendix.m2ee.server.handler.RuntimeHandler.handle(RuntimeHandler.java:45) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:111) at org.eclipse.jetty.server.Server.handle(Server.java:351) at org.eclipse.jetty.server.AbstractHttpConnection.handleRequest(AbstractHttpConnection.java:454) at org.eclipse.jetty.server.AbstractHttpConnection.headerComplete(AbstractHttpConnection.java:890) at org.eclipse.jetty.server.AbstractHttpConnection$RequestHandler.headerComplete(AbstractHttpConnection.java:944) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:634) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:230) at org.eclipse.jetty.server.AsyncHttpConnection.handle(AsyncHttpConnection.java:77) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.handle(SelectChannelEndPoint.java:609) at org.eclipse.jetty.io.nio.SelectChannelEndPoint$1.run(SelectChannelEndPoint.java:45) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:599) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:534) at java.lang.Thread.run(Thread.java:662) Caused by: java.io.IOException: De externe host heeft een verbinding verbroken at sun.nio.ch.SocketDispatcher.write0(Native Method) at sun.nio.ch.SocketDispatcher.write(SocketDispatcher.java:33) at sun.nio.ch.IOUtil.writeFromNativeBuffer(IOUtil.java:69) at sun.nio.ch.IOUtil.write(IOUtil.java:40) at sun.nio.ch.SocketChannelImpl.write(SocketChannelImpl.java:336) at org.eclipse.jetty.io.nio.ChannelEndPoint.flush(ChannelEndPoint.java:292) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.flush(SelectChannelEndPoint.java:344) at org.eclipse.jetty.io.nio.ChannelEndPoint.flush(ChannelEndPoint.java:343) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.flush(SelectChannelEndPoint.java:319) at org.eclipse.jetty.http.HttpGenerator.flushBuffer(HttpGenerator.java:879) at org.eclipse.jetty.http.AbstractGenerator.blockForOutput(AbstractGenerator.java:518) at org.eclipse.jetty.server.HttpOutput.write(HttpOutput.java:182) at org.eclipse.jetty.server.HttpOutput.write(HttpOutput.java:101) at org.apache.commons.io.IOUtils.copyLarge(IOUtils.java:1720) at org.apache.commons.io.IOUtils.copyLarge(IOUtils.java:1696) at org.apache.commons.io.IOUtils.copy(IOUtils.java:1671) at com.mendix.externalinterface.connector.ResourceRequestHandler.processRequest(ResourceRequestHandler.java:70) at com.mendix.externalinterface.connector.MxRuntimeConnector.processRequest(MxRuntimeConnector.java:63) at com.mendix.core.MxRuntime.processRequest(MxRuntime.java:916) at com.mendix.m2ee.server.handler.RuntimeHandler.handle(RuntimeHandler.java:45) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:111) at org.eclipse.jetty.server.Server.handle(Server.java:351) at org.eclipse.jetty.server.AbstractHttpConnection.handleRequest(AbstractHttpConnection.java:454) at org.eclipse.jetty.server.AbstractHttpConnection.headerComplete(AbstractHttpConnection.java:890) at org.eclipse.jetty.server.AbstractHttpConnection$RequestHandler.headerComplete(AbstractHttpConnection.java:944) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:634) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:230) at org.eclipse.jetty.server.AsyncHttpConnection.handle(AsyncHttpConnection.java:77) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.handle(SelectChannelEndPoint.java:609) at org.eclipse.jetty.io.nio.SelectChannelEndPoint$1.run(SelectChannelEndPoint.java:45) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:599) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:534) at java.lang.Thread.run(Thread.java:662)
