Hi list,
I have 3 Tomcat 5.0.19 instances running with Apache 2.019 and JK2.
I did a simple load testing with JMeter last night and stopped it just
before I went home, so right now there's no incoming request whatsoever, but
TOP still shows heavy memory usage and swapping, it looks like even though
the load has subsided, Tomcat has not released the memory, what can I do
except restart the Tomcat instances to release the memory?
I'm not sure if this is a valid question, so I apologize if I seem to be
lack of some basic understanding of how things work.
Thanks in advance.
Also the tomcats are started with -Xms64 -Xmx256
