Here is a chat from #tom...@freenode that pretty much explains it: * nDuff tries to reproduce <nDuff> umm <nDuff> it's three process table entries, but that's just threads <nDuff> it's only one copy of tomcat <nDuff> NOTABUG. <nDuff> mlaci, if you do a pstree on the lowest PID, you'll see that the other two are its children. <mlaci> nDuff, yeah, that's true, but that doesn't make me understand why multiple instances are started by default <nDuff> mlaci, they _aren't_ multiple instances, that's the point <nDuff> mlaci, if you start Apache httpd with a multithreaded MPM, the threads will show up as separate process table entries... <nDuff> mlaci, ...but that doesn't mean there's more than one copy of Apache in memory. <nDuff> mlaci, ...looking more closely, it appears that the first two are part of jsvc; they're normal and harmless. <nDuff> mlaci, ...see the "how jsvc works" section at http://commons.apache.org/daemon/jsvc.html <mlaci> nDuff, the last url pretty much explains it. so 1) these processes are all needed to make tomcat work and 2) they don't consume 3 times more memory than a single tomcat process? <nDuff> mlaci, (1) to make tomcat work in such a way that it can be controlled via jsvc commands, yes; (2) no, absolutely not.
