---------------------------------------
Summary: Memory leak with apache artemis 2.1.0
Key: ARTEMIS-1298
URL: https://issues.apache.org/jira/browse/ARTEMIS-1298
Project: ActiveMQ Artemis
Issue Type: Bug
Components: MQTT
Affects Versions: 2.1.0
Reporter: REGINA Patrick
Fix For: 2.1.0
hi,
With my broker Mqtt configuration, it seems a memory leak appears after 16
hours.
Indeed the memory increase but each full GC and GC not release enough memory.
my JAVA_ARGS=" -XX:+PrintClassHistogram -XX:+UseG1GC -XX:+AggressiveOpts
-XX:+UseFastAccessorMethods -Xms512M -Xmx2G"
Please found below my broker.xml :
{panel:title=My broker.xml}
