I am sure this us a silly question, but did you put a load on it? If it's
round-robin that's one thing.. if it's SMART load-balancing.. then you would
have to hammer on it for it to push to the second machine (assuming your
configuration is correct, of course).

We use a Foundry Server Iron switch to load balance our Tomcat application

if i do load balancing with tomcat (w/ mod_jk), what happens if the two tomcat servers
at the same time execute a synchronized method? will they know that they mustn't

With mod_jk, even in load balancing mode, a request is allways
sent a a SINGLE tomcat !
will they know that they mustn't execute
it concurrently
the load balancing will work but not session failover.
We use mod_jserv in test and production on Linux and FreeBSD, and I can verify
that the VM failover works on both. We have developers who work on NT and have
set up load balancing on their boxes, but we don't use in anger.
For testing, note

Ok,
I have implemented load balancing with mod_jk (sticky sessions). Seems
to work well. However, I need to implement load balancing with non-sticky
sessions. (Teflon sessions? :) ) I need all of the tomcat servers to be
aware of all the sessions currently in use on the system

all requests are processes via port 10101.
