Hi all,
I'm playing with Clustering on Tomcat 4.1.30 (1 Solaris-Server called eules
with 2 tomcat instances).
The only usefull solution I found, is your replicator
(tomcat-replication.jar).
But there are some problems and I hope that you can help me. :)
When I start tomcat 1, I'll see the following message/exception:
-- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---

I don't know, if this is really a problem, but when I start tomcat 2, I'll
see the following message/exception:

TIMING OUT

This happens directly after starting the instances without browsing the
content of the containers.
Do you have an idea, what the reasion is?
Thanx a lot
