FW: multiple tomcat processes running on linux

Hi,
 
I've my application running on the following environment
 
-Tomcat 5.0.16
-Red Hat Enterprise Linux AS release 3 (Taroon Update 4) 2.4.21
32.0.1.ELsmp (32-bit)
 
When I give ps -ef | grep tomcat, it shows multiple processes running &
all of them grabbing majority of the available memory
 
Is it something to do with OS ?
 
What can I do to stop the multiple processes?
 
Thanks in advance
 
Anil

You are running on an old 2.4 kernel - and you are only seeing 1 process
and lots of threads...

Update to a 2.6 kernel as soon as possible if you want to do anything
serious with Tomcat.

As for the memory - It uses as much as you tell it to use.

That's covered in the Linux section of the FAQ: Linux ps reports
multiple threads as separate processes. Try adjusting the number of
threads in server.xml.
