Damien Hollis created ARTEMIS-739: ------------------------------------- Summary: Large messages failing with "(Too many open files)" Key: ARTEMIS-739 URL: https://issues.apache.org/jira/browse/ARTEMIS-739 Project: ActiveMQ Artemis Issue Type: Bug Affects Versions: 1.3.0 Reporter: Damien Hollis Priority: Critical
We are processing a large number of large messages and many of them are being put into the dead-letter queue as part of a transaction rollback. I suspect that during the rollback the large message is not being released properly and as a result the error below eventually occurs. This may be a more general issue but so far we have only seen this issue when processing messages successfully (although another person in the team mentioned that there seem to be a lot of large messages hanging around). I noted we are not using the latest version, so I'm in the process of creating a new build and I will test with version 1.4 later today or tomorrow. {noformat} org.apache.activemq.artemis.core.server | AMQ222010: Critical IO Error, shutting down the server. file=NIOSequentialFile /var/data/artemis/large-messages/2147660860.msg, message=/var/data/artemis/large-messages/2147660860.msg (Too many open files) org.apache.activemq.artemis.api.core.ActiveMQIOErrorException: /var/data/artemis/large-messages/2147660860.msg (Too many open files) at org.apache.activemq.artemis.core.io.nio.NIOSequentialFile.open(NIOSequentialFile.java:101) at org.apache.activemq.artemis.core.io.nio.NIOSequentialFile.open(NIOSequentialFile.java:85) at org.apache.activemq.artemis.core.persistence.impl.journal.LargeServerMessageImpl$DecodingContext.open(LargeServerMessageImpl.java:426) at org.apache.activemq.artemis.core.server.impl.ServerConsumerImpl$LargeMessageDeliverer.deliver(ServerConsumerImpl.java:1131) at org.apache.activemq.artemis.core.server.impl.ServerConsumerImpl.proceedDeliver(ServerConsumerImpl.java:414) at org.apache.activemq.artemis.core.server.impl.QueueImpl.proceedDeliver(QueueImpl.java:2464) at org.apache.activemq.artemis.core.server.impl.QueueImpl.deliver(QueueImpl.java:1956) at org.apache.activemq.artemis.core.server.impl.QueueImpl.access$1500(QueueImpl.java:99) at org.apache.activemq.artemis.core.server.impl.QueueImpl$DeliverRunner.run(QueueImpl.java:2695) at org.apache.activemq.artemis.utils.OrderedExecutorFactory$OrderedExecutor$ExecutorTask.run(OrderedExecutorFactory.java:103) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: java.io.FileNotFoundException: /var/data/artemis/large-messages/2147660860.msg (Too many open files) at java.io.RandomAccessFile.open0(Native Method) at java.io.RandomAccessFile.open(RandomAccessFile.java:316) at java.io.RandomAccessFile.<init>(RandomAccessFile.java:243) at org.apache.activemq.artemis.core.io.nio.NIOSequentialFile.open(NIOSequentialFile.java:91) ... 12 common frames omitted {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
