Subject RE: Tomcat 4.x and Java Processes
Date Wed, 08 Jan 2003 00:24:16 GMT
On Linux "ps -fx" will not show the tomcat processes if tomcat is run under
a different account. I think "ps -fx" just shows processes running under
root??? To see all processes, I had to do "ps -fxa" to see my tomcat
processes running under the tomcat4 account.

Yes, sorry, I forgot to mention that.  Are there options for threading
on linux?  I think on Solaris, you can do "green" or native threads.  If
so, would a change in this setting reduce the JVM to a single pid?

Thanks for the quick reply!

Are you using Linux? Linux shows in-process threads as processes. If you
are running Linux, then you are seeing threads within the Java process.
You would expect to see a number of threads even with your simple
config.
