This is reproducible in WildFly 10.0.0.Final as well. I created EJBCLIENT-156 and sent a pull request for an engineering review. Enrique González Martínez <elguardian> updated the status of jira JBEAP-4284 to Resolved Verified with EAP 6.4.10.CP.CR1 Jiri Pallich <jpallich> updated the status of jira JBEAP-4284 to Closed Retroactively bulk-closing issues from released EAP 6.4 cummulative patches.

Created attachment 1148107 [details] remote-async-void-slsb-dbuffer-leak.zip Description of problem: JBoss Remoting enabled direct buffer from 3.3.7.Final, which is included in EAP 6.4.6 (by BZ-1288664/REM3-208). This causes an OOME in direct buffer when a remote client calls an asynchronous method which has return type void. ~~~ Apr 18, 2016 2:22:26 PM org.xnio.ChannelListeners invokeChannelListener ERROR: A channel event listener threw an exception java.lang.OutOfMemoryError: Direct buffer memory at java.nio.Bits.reserveMemory(Bits.java:693) at java.nio.DirectByteBuffer.<init>(DirectByteBuffer.java:123) at java.nio.ByteBuffer.allocateDirect(ByteBuffer.java:311) at org.xnio.BufferAllocator$2.allocate(BufferAllocator.java:60) at org.xnio.BufferAllocator$2.allocate(BufferAllocator.java:58) at org.xnio.ByteBufferSlicePool.allocate(ByteBufferSlicePool.java:86) at org.jboss.remoting3.remote.RemoteConnection.allocate(RemoteConnection.java:75) at org.jboss.remoting3.remote.RemoteConnectionChannel.allocate(RemoteConnectionChannel.java:581) at org.jboss.remoting3.remote.InboundMessage.allocate(InboundMessage.java:190) at org.jboss.remoting3.remote.InboundMessage.doSendCloseMessage(InboundMessage.java:104) at org.jboss.remoting3.remote.InboundMessage.handleIncoming(InboundMessage.java:243) at org.jboss.remoting3.remote.RemoteConnectionChannel.handleMessageData(RemoteConnectionChannel.java:474) at org.jboss.remoting3.remote.RemoteReadListener.handleEvent(RemoteReadListener.java:291) at org.jboss.remoting3.remote.RemoteReadListener.handleEvent(RemoteReadListener.java:46) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:72) at org.xnio.channels.TranslatingSuspendableChannel.handleReadable(TranslatingSuspendableChannel.java:189) at org.xnio.channels.TranslatingSuspendableChannel$1.handleEvent(TranslatingSuspendableChannel.java:103) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:72) at org.xnio.nio.NioHandle.run(NioHandle.java:90) at org.xnio.nio.WorkerThread.run(WorkerThread.java:198) ~~~ Version-Release number of selected component (if applicable): EJB client (jboss-client.jar) of EAP 6.4.6 How reproducible: Always. Steps to Reproduce: 1. Unzip the reproducer and build an EJB and its client. ~~~ cd remote-async-void-slsb-dbuffer-leak vi src/test/java/TestMainDBufferLeak.java #The default is against localhost without authentication. mvn package ~~~ 2. Deploy target/remote-async-void-slsb-dbuffer-leak-1.0.0.jar to a standalone server 3. Run the test client ~~~ java -cp $EAP646_HOME/bin/client/jboss-client.jar:target/test-classes:target/remote-async-void-slsb-dbuffer-leak-1.0.0.jar \ -Xms100m -Xmx100m TestMainDBufferLeak ~~~ Actual results: "java.lang.OutOfMemoryError: Direct buffer memory" as in the description. Expected results: No memory leaks. Additional info: Add command line option "-Djboss.remoting.pooled-buffers=false" for the client as a workaround.
