RestStoreTest.tearDown intermittent failure ------------------------------------------- Key: ISPN-8217 URL: https://issues.jboss.org/browse/ISPN-8217 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Affects Versions: 9.1.0.Final Reporter: Ryan Emerson Assignee: Ryan Emerson Fix For: 9.1.3.Final The test fails intermittently with the following: {code:java} io.netty.channel.ChannelException: eventfd_write() failed: Bad file descriptor at io.netty.channel.epoll.Native.eventFdWrite(Native Method) at io.netty.channel.epoll.EpollEventLoop.wakeup(EpollEventLoop.java:126) at io.netty.util.concurrent.SingleThreadEventExecutor.shutdownGracefully(SingleThreadEventExecutor.java:589) at io.netty.util.concurrent.MultithreadEventExecutorGroup.shutdownGracefully(MultithreadEventExecutorGroup.java:163) at org.infinispan.server.core.transport.NettyTransport.stop(NettyTransport.java:161) at org.infinispan.server.core.AbstractProtocolServer.stop(AbstractProtocolServer.java:144) at org.infinispan.persistence.rest.RestStoreTest.tearDown(RestStoreTest.java:73) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) ... Removed 18 stack frames {code} I believe this is caused by Netty not closing connections properly. See [here|http://netty.io/news/2017/07/06/4-0-49-Final-4-1-13-Final.html]. Upgrading Netty to the latest version should hopefully resolve this issue.
