> Key: QPID-7475
> URL: https://issues.apache.org/jira/browse/QPID-7475
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-6.1
> Reporter: Alex Rudyy
>
> With default memory settings (512M of heap and 1.5G of direct memory) Broker should allow publishing of 508896 messages of size 1000bytes according to [the formula for estimation of heap size|http://qpid.apache.org/releases/qpid-java-6.0.4/java-broker/book/Java-Broker-Runtime-Memory.html#Java-Broker-Runtime-Memory-Tuning]. However, in my test with single connection and single queue I only managed to publish 367301 persistent messages of size 1000bytes . The heap space was fully occupied and Full GC was running nonstop making broker unusable. I can publish 508896 persistent messages with 0-10 protocol without any issue. We need top optimize memory consumption by persistent messages on 0-9 path.
