Re: using htop, i see many tomcat processes?

[Tim Watts]

You may have the thread view active.  Each thread gets its own PID.  I
don't know about htop, but in top H (i.e. capital H) toggles this.

And it's CATALINA_OPTS not CATALINA_OPT.

 Can someone make sense of this to me? :)

Unless you meant CATALINA_OPTS, you aren't changing anything in
catalina.sh. Oh, and you should be using setenv.sh not catalina.sh.

 When I run htop, I see many instances of the tomcat process.

See Tim's response about threads versus processes.

As for the process with Xmx 128m, you're going to have to look a
little more closely at the exact command line to figure out how it was
started -- we can't really help you with that.
