Hi, I'm expecting some problems while running a load test on camel-netty component.
This is the route configuration: <route id="rtRead"> <from uri="netty:tcp://pos-tcp-server.host:9000?decoder=#myDecoder&encoder=#myEncoder&sync=true&reuseAddress=true&synchronous=false&workerCount=100&maximumPoolSize=100”/> <log message="Lendo ${body}" /> <to uri="ejb:local/GatewayBean?method=process" /> </route> After some test cycles, we receive some exceptions like this: 2013-08-13 11:25:33,398 WARNING [org.jboss.netty.channel.DefaultChannelPipeline] [New I/O worker #32] An exception was thrown by a user handler while handling an exception event ([id: 0x8c7d41bd, /10.10.0.28:53469 => /10.11.234.38:9000] EXCEPTION: java.lang.OutOfMemoryError: unable to create new native thread) java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:640) at java.util.concurrent.ThreadPoolExecutor.addIfUnderCorePoolSize(ThreadPoolExecutor.java:703) at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:652) at org.jboss.netty.handler.execution.MemoryAwareThreadPoolExecutor.doUnorderedExecute(MemoryAwareThreadPoolExecutor.java:452) at org.jboss.netty.handler.execution.OrderedMemoryAwareThreadPoolExecutor$ChildExecutor.execute(OrderedMemoryAwareThreadPoolExecutor.java:292) at org.jboss.netty.handler.execution.OrderedMemoryAwareThreadPoolExecutor.doExecute(OrderedMemoryAwareThreadPoolExecutor.java:242) at org.jboss.netty.handler.execution.MemoryAwareThreadPoolExecutor.execute(MemoryAwareThreadPoolExecutor.java:437) at org.jboss.netty.handler.execution.ExecutionHandler.handleUpstream(ExecutionHandler.java:172) at org.jboss.netty.channel.Channels.fireExceptionCaught(Channels.java:533) at org.jboss.netty.channel.Channels$7.run(Channels.java:507) at org.jboss.netty.channel.socket.ChannelRunnableWrapper.run(ChannelRunnableWrapper.java:41) at org.jboss.netty.channel.socket.nio.AbstractNioWorker.processEventQueue(AbstractNioWorker.java:453) at org.jboss.netty.channel.socket.nio.AbstractNioWorker.run(AbstractNioWorker.java:330) at org.jboss.netty.channel.socket.nio.NioWorker.run(NioWorker.java:35) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) It sounds strange, our test case has only 5 simultaneous opened connections. For me we are heaving some leak of threads or we are having some problems to close the SocketChannel correctly.
