Yes i've configured the Tomcat environment -Xms, -Xmm but i think it doesn't work, because it's consume the server memory until 145 Mb per process i need to limit the number of java proccess and the memory that they consume on my Linux Red Hat 7.3 server

thanks a lot

I not shure which problem you have :
- Why do I have so many processes
 (You havn't, that are threads, search google or the archives on that one)
- Why does the process take this amount of memory Depens on several factors. (Memory setting of the vm, amount of servlets, jsp's, number of features you use in tomcat, current number of active sessions, ....)
- How can I give the process more memory
 Set the option in the environment variable CATALINA_OPTS or JAVA_OPTS
 befor starting tomcat.

Hi i have installed apache 13.24 with 2 tomcats 4.0.3 with loadbalancer is woring fine but the problem when i'm using the ps -ef | grep java command i've saw many java process justa like these: 21430 root 15 0 139M 139M 49444 S 0.0 13.8 0:00 java 21431 root 15 0 139M 139M 49444 S 0.0 13.8 0:00 java 21443 root 15 0 139M 139M 49444 S 0.0 13.8 0:07 java 21444 root 20 0 139M 139M 49444 S 0.0 13.8 0:00 java 21445 root 20 0 139M 139M 49444 S 0.0 13.8 0:00 java 21446 root 15 0 139M 139M 49444 S 0.0 13.8 0:06 java 21454 root 15 0 139M 139M 49444 S 0.0 13.8 0:00 java 21457 root 15 0 139M 139M 49444 S 0.0 13.8 0:00 java 21458 root 15 0 139M 139M 49444 S 0.0 13.8 0:00 java 21460 root 15 0 139M 139M 49444 S 0.0 13.8 0:00 java 21462 root 15 0 139M 139M 49444 S 0.0 13.8 0:00 java 21464 root 15 0 139M 139M 49444 S 0.0 13.8 0:00 java 21466 root 15 0 139M 139M 49444 S 0.0 13.8 0:00 java 21468 root 16 0 139M 139M 49444 S 0.0 13.8 0:04 java 21469 root 15 0 139M 139M 49444 S 0.0 13.8 0:03 java

looking the internet, the solution is use the -Xmx , -Xms and use the className="org.apache.tomcat.service.PoolTcpConnector" and i'm working with Ajp13

 <Connector className="org.apache.tomcat.service.PoolTcpConnector"> <Parameter name="handler" value="org.apache.tomcat.service.connector.Ajp12ConnectionHandler"/> <Parameter name="port" value="8007"/> <Parameter name="max_threads" value="30"/> <Parameter name="max_spare_threads" value="20"/> <Parameter name="min_spare_threads" value="5" /> </Connector>
Thanks
Fabian
