nicolas desmaziers created WFLY-4480: ---------------------------------------- Summary: Websocket exception using async remote Key: WFLY-4480 URL: https://issues.jboss.org/browse/WFLY-4480 Project: WildFly Issue Type: Bug Components: Web Sockets Affects Versions: 9.0.0.Beta2 Reporter: nicolas desmaziers Assignee: Stuart Douglas Sending binary messages on the AsyncRemote endpoint throws an error in the log: 21:11:28,747 ERROR [org.xnio.listener] (default I/O-6) XNIO001007: A channel event listener threw an exception: java.lang.IllegalStateException: XNIO000017: Buffer was already freed at org.xnio.ByteBufferSlicePool$PooledByteBuffer.getResource(ByteBufferSlicePool.java:206) at org.xnio.ByteBufferSlicePool$PooledByteBuffer.getResource(ByteBufferSlicePool.java:176) at io.undertow.server.protocol.framed.AbstractFramedChannel.flushSenders(AbstractFramedChannel.java:490) at io.undertow.server.protocol.framed.AbstractFramedChannel$FrameWriteListener.handleEvent(AbstractFramedChannel.java:793) at io.undertow.server.protocol.framed.AbstractFramedChannel$FrameWriteListener.handleEvent(AbstractFramedChannel.java:790) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) at org.xnio.conduits.WriteReadyHandler$ChannelListenerHandler.writeReady(WriteReadyHandler.java:65) at org.xnio.nio.NioSocketConduit.handleReady(NioSocketConduit.java:93) at org.xnio.nio.WorkerThread.run(WorkerThread.java:539) This happens after a few minutes and generally the number of errors increase rapidly and we can easily have a 2Go log after a few hours. Code is: session.getAsyncRemote.sendBinary(event.asReadOnlyBuffer(), new SendHandler(){ override def onResult(result:SendResult) { } }) It worked well with wildly 9.0 alpha 1 but bug appeared with beta 2. I generally receive a close event on the web socket session after the error logging. -- This message was sent by Atlassian JIRA (v6.3.11#6341)
