Hi All, I have below configuration for my java actvemq process where Xmx is 15360M but when I see the process usage of memory using glance I see RSS 41.8gb and VSS 51.6gb . pmap <process_id>|grep total gives me total 54059348K. I am not sure what is happening in activemq that is causing this much amount of memory being utilized. While heap usage is pretty low till 60%.
In the output of pmap I see lot of anon blocks. Please find attached PMAP output /XXXXX 111922 1 22 14:30 pts/0 00:04:26 /u/users/user/jdk1.7.0_71/bin/java -Xms1024M -Xmx15360M -Xss512K -XX:+UseG1GC -XX:NewRatio=4 -XX:InitiatingHeapOccupancyPercent=45 -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:/x/logs/AMQGC.log -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=20M -Djava.util.logging.config.file=logging.properties -Djava.security.auth.login.config=/u/users/user/POSInterfaces/apache-activemq-5.13.2//conf/login.config -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote -Djava.awt.headless=true -Djava.io.tmpdir=/u/users/user/POSInterfaces/apache-activemq-5.13.2//tmp -Dactivemq.classpath=/u/users/user/POSInterfaces/apache-activemq-5.13.2//conf:/u/users/user/POSInterfaces/apache-activemq-5.13.2//../lib/: -Dactivemq.home=/u/users/user/POSInterfaces/apache-activemq-5.13.2/ -Dactivemq.base=/u/users/user/POSInterfaces/apache-activemq-5.13.2/ -Dactivemq.conf=/u/users/user/POSInterfaces/apache-activemq-5.13.2//conf -Dactivemq.data=/u/users/user/POSInterfaces/apache-activemq-5.13.2//data -jar /u/users/user/POSInterfaces/apache-activemq-5.13.2//bin/activemq.jar start/ pmap.txt <http://activemq.2283324.n4.nabble.com/file/t378515/pmap.txt> -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
