Hi,

Just taking a look at 'top' and noticed the following:

 top
PID   USER   PR   NI   VIRT   RES   SHR   S   %CPU   %MEM   TIME+   COMMAND
5983   root   24   0   796m   312m   17m   S   0   15.4   280:08.26   java

Code: Select all

 ps ax | grep java
PID   TTY   STAT   TIME    COMMAND
5983   ?   Sl   280:08   /usr/java/jre1.5.0_11/bin/java -server -Djava.net.preferIPv4Stack=true -Dscalix.instance=/var/opt/scalix/ml -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file=/var/opt/scalix/ml/tomcat/conf/logging.properties -Djava.endorsed.dirs=/opt/scalix-tomcat/common/endorsed -classpath /usr/java/jre1.5.0_11/lib/tools.jar:/opt/scalix-tomcat/bin/bootstrap.jar:/opt/scalix-tomcat/bin/commons-logging-api.jar -Dcatalina.base=/var/opt/scalix/ml/tomcat -Dcatalina.home=/opt/scalix-tomcat -Djava.io.tmpdir=/var/opt/scalix/ml/tomcat/temp org.apache.catalina.startup.Bootstrap start

seems quite alot of resources, is this normal?

Hi William!

This is absolutely normal to me, by the way how memory is allocated for tomcat?

The result of top -p 23238 is as below:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
23238 root 23 0 340m 100m 14m S 0.0 40.4 0:44.89 java

and result of ps ax | grep java is:

# ps ax | grep java
23238 pts/2 Sl 0:44 /usr/java/jre1.5.0_06/bin/java -server -Djava.net.preferIPv4Stack=true -Xms124m -Xmx124m -Dscalix.instance=/var/opt/scalix/s4 -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file=/var/opt/scalix/s4/tomcat/conf/logging.properties -Djava.endorsed.dirs=/opt/scalix-tomcat/common/endorsed -classpath /usr/java/jre1.5.0_06/lib/tools.jar:/opt/scalix-tomcat/bin/bootstrap.jar:/opt/scalix-tomcat/bin/commons-logging-api.jar -Dcatalina.base=/var/opt/scalix/s4/tomcat -Dcatalina.home=/opt/scalix-tomcat -Djava.io.tmpdir=/var/opt/scalix/s4/tomcat/temp org.apache.catalina.startup.Bootstrap start

Thanks,
