Hello, I have tomcat 4.1.10 on a red hat Linux server 7.3 with the j2sdk141,
When I start the tomcat4 service, all is OK and the tomcat server run. BUT, when I look the memory usage (with TOP utility), I have this result : 11:31am up 12 days, 2:18, 2 users, load average: 0,00, 0,00, 0,00 90 processes: 87 sleeping, 3 running, 0 zombie, 0 stopped CPU states: 0,0% user, 0,5% system, 0,0% nice, 99,4% idle Mem: 514340K av, 479748K used, 34592K free, 0K shrd, 75716K buff Swap: 1048120K av, 35016K used, 1013104K free 216648K cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND 19954 tomcat4 25 0 33584 32M 10464 S 0,0 6,5 0:05 java 19957 tomcat4 15 0 33584 32M 10464 S 0,0 6,5 0:00 java 19958 tomcat4 15 0 33584 32M 10464 S 0,0 6,5 0:00 java 19959 tomcat4 15 0 33584 32M 10464 S 0,0 6,5 0:00 java 19960 tomcat4 15 0 33584 32M 10464 S 0,0 6,5 0:00 java 19961 tomcat4 15 0 33584 32M 10464 R 0,0 6,5 0:00 java 19962 tomcat4 20 0 33584 32M 10464 S 0,0 6,5 0:00 java 19963 tomcat4 16 0 33584 32M 10464 S 0,0 6,5 0:00 java 19964 tomcat4 16 0 33584 32M 10464 S 0,0 6,5 0:01 java 19966 tomcat4 15 0 33584 32M 10464 S 0,0 6,5 0:00 java 19967 tomcat4 15 0 33584 32M 10464 S 0,0 6,5 0:00 java 19968 tomcat4 15 0 33584 32M 10464 S 0,0 6,5 0:00 java 19969 tomcat4 15 0 33584 32M 10464 S 0,0 6,5 0:00 java 19970 tomcat4 15 0 33584 32M 10464 S 0,0 6,5 0:00 java 19971 tomcat4 15 0 33584 32M 10464 S 0,0 6,5 0:00 java 19972 tomcat4 15 0 33584 32M 10464 S 0,0 6,5 0:00 java 19973 tomcat4 15 0 33584 32M 10464 S 0,0 6,5 0:00 java So, My first question is : why tomcat use all the memory while there is no users connected (or just one) ? My second question is : how much memory is needed if I want to use tomcat with many users (500, 1000,...) ? I already read in the forum Tomcat don't manage the memory, it is the JVM... so why the jvm use so many processes ? -- To unsubscribe, e-mail: <mailto:tomcat-dev-unsubscribe@;jakarta.apache.org> For additional commands, e-mail: <mailto:tomcat-dev-help@;jakarta.apache.org>
