Hello FreeBSD team, we are hosting a Java web application on our FreeBSD 9.2 server on which Tomcat 7.0 is used as runtime environment. During monitoring the Java process we have found out the Java process allocates 9GB of memory: 39819 www 35 20 0 9051M 439M uwait 4 0:31 0.00% jsvc www 39819 0.0 1.4 9268296 449704 ?? IJ 4:05PM 0:30.60 /usr/local/bin/jsvc -java-home /usr/local/openjdk6 -server -user www -pidfile /var/run/tomcat7.pid -wait 30 -out For this reason, we have reconfigured the Tomcat by setting up the minimum and maximum heap size in file /usr/local/<TOMCAT>/bin/setenv.sh with following values: CATALINA_OPTS="$CATALINA_OPTS -Xms128m" CATALINA_OPTS="$CATALINA_OPTS -Xmx512m" After the Tomcat reboot the allocation remains at this very high consumption. Our question at this point: [1] Is this problem already known? [2] What are possible options regarding the setup which could solve the problem? If you need further information, please do not hesitate to contact us. Thanks for your support. -- Best regards, Uwe
