应用错误收集

我在maven中运行junit测试时遇到此错误：com.datastax.driver.core.TransportException：[/127.0.0.1]频道已关闭

最终会导致OutOfMemory异常。

我正在使用cassandra-unit来运行嵌入式cassandra集群。在几个测试用例之后，它开始抛出以下错误： java.util.concurrent.ExecutionException: com.datastax.driver.core.TransportException: [/127.0.0.1] Channel has been closed at com.google.common.util.concurrent.AbstractFuture$Sync.getValue(AbstractFuture.java:306) at com.google.common.util.concurrent.AbstractFuture$Sync.get(AbstractFuture.java:293) at com.google.common.util.concurrent.AbstractFuture.get(AbstractFuture.java:116) at com.datastax.driver.core.ControlConnection.refreshSchema(ControlConnection.java:265) at com.datastax.driver.core.ControlConnection.refreshSchema(ControlConnection.java:230) at com.datastax.driver.core.Cluster$Manager$2.run(Cluster.java:951) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:439) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:895) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:918) at java.lang.Thread.run(Thread.java:680) Caused by: com.datastax.driver.core.TransportException: [/127.0.0.1] Channel has been closed at com.datastax.driver.core.Connection$Dispatcher.channelClosed(Connection.java:566) at org.jboss.netty.channel.SimpleChannelUpstreamHandler.handleUpstream(SimpleChannelUpstreamHandler.java:88) at org.jboss.netty.channel.DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline.java:560) at org.jboss.netty.channel.DefaultChannelPipeline$DefaultChannelHandlerContext.sendUpstream(DefaultChannelPipeline.java:787) at org.jboss.netty.handler.codec.oneone.OneToOneDecoder.handleUpstream(OneToOneDecoder.java:60) at org.jboss.netty.channel.DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline.java:560) at org.jboss.netty.channel.DefaultChannelPipeline$DefaultChannelHandlerContext.sendUpstream(DefaultChannelPipeline.java:787) at org.jboss.netty.handler.codec.oneone.OneToOneDecoder.handleUpstream(OneToOneDecoder.java:60) at org.jboss.netty.channel.DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline.java:560) at org.jboss.netty.channel.DefaultChannelPipeline$DefaultChannelHandlerContext.sendUpstream(DefaultChannelPipeline.java:787) at org.jboss.netty.handler.codec.frame.FrameDecoder.cleanup(FrameDecoder.java:493) at org.jboss.netty.handler.codec.frame.FrameDecoder.channelClosed(FrameDecoder.java:371) at org.jboss.netty.channel.SimpleChannelUpstreamHandler.handleUpstream(SimpleChannelUpstreamHandler.java:88) at org.jboss.netty.channel.DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline.java:560) at org.jboss.netty.channel.DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline.java:555) at org.jboss.netty.channel.Channels.fireChannelClosed(Channels.java:468) at org.jboss.netty.channel.socket.nio.AbstractNioWorker.close(AbstractNioWorker.java:351) at org.jboss.netty.channel.socket.nio.NioWorker.read(NioWorker.java:93) at org.jboss.netty.channel.socket.nio.AbstractNioWorker.process(AbstractNioWorker.java:107) at org.jboss.netty.channel.socket.nio.AbstractNioSelector.run(AbstractNioSelector.java:312) at org.jboss.netty.channel.socket.nio.AbstractNioWorker.run(AbstractNioWorker.java:88) at org.jboss.netty.channel.socket.nio.NioWorker.run(NioWorker.java:178) at org.jboss.netty.util.ThreadRenamingRunnable.run(ThreadRenamingRunnable.java:108) at org.jboss.netty.util.internal.DeadLockProofWorker$1.run(DeadLockProofWorker.java:42)

我试图为进程提供足够的内存（-Xmx2048m -XX：MaxPermSize = 512m），但它没有帮助

通过cassandra-unit运行测试时出现异常
