I have a CentOS+CPanel+Tomcat+Spring+MySQL+Flex architecture.

I need to monitor my application’s memory because Tomcat is crashing from time to time. I read that JMX + Jconsole its a great choice. So i’m setting those variables in CATALINA_OPTS (in CPanel, you add the options in a file called tomcat.options). But I get an invalid port error. I tried with several port numbers: 8181, 8999, 3000. This is a tomcat.options file that doesn’t work:

-Dcom.sun.management.jmxremote  
-Dcom.sun.management.jmxremote.port=8999  
-Dcom.sun.management.jmxremote.ssl=false  
-Dcom.sun.management.jmxremote.authenticate=false  
-Djava.rmi.server.hostname=li170-64

I googled the error and could not find anyone else with the same error. What’s wrong?
