Subject [jira] [Created] (APLO-360) regular, reproducable OutOfMemory exceptions
Date Thu, 26 Jun 2014 16:14:24 GMT
Daniel Miles created APLO-360:
---------------------------------

             Summary: regular, reproducable OutOfMemory exceptions
                 Key: APLO-360
                 URL: https://issues.apache.org/jira/browse/APLO-360
             Project: ActiveMQ Apollo
          Issue Type: Bug
          Components: apollo-broker
    Affects Versions: 1.7
         Environment:  * OS: Amazon Linux AMI release 2014.03 (centos-like)
 * CPU: Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GH
 * MemTotal: 3843028 kB
 * Startup command: apollo -ea -server -XX:+AggressiveOpts -XX:+OptimizeStringConcat -XX:+UseFastAccessorMethods
-XX:+UseBiasedLocking -Xmx2662m -Xms128m -Dcom.sun.management.jmxremote -Dapollo.home=/opt/apache-apollo-1.7
-Dapollo.base=/var/lib/subscriptions -classpath /opt/apache-apollo-1.7/lib/apollo-boot.jar
org.apache.activemq.apollo.boot.Apollo /var/lib/subscriptions/lib\;/opt/apache-apollo-1.7/lib
org.apache.activemq.apollo.cli.Apollo run
 * Java: OpenJDK 64-Bit Server VM 1.7.0_55
            Reporter: Daniel Miles
         Attachments: log.tar.bz2

Apollo has been failing under load, and I can consistently reproduce it with this formula.
I've attached two things to this bug report:
 * All apollo logs
 * The load-test application (both source code and compiled binary)
After a few hours of load testing (one producer, five consumers, roughly 7000 messages/second,
message size 1.4k), leveldb has a "Short Write" exception then Apollo goes into recovery mode
and runs out of memory. All logs are attached, relevant section of stacktrace.log looks like
this:
