this code uses Java.nio packages.
if you are running this as a non privileged user, there is a chance that it fails to
open the socket.
as you can see, the problem is in native code,
java.io.IOException: No such file or directory
at sun.nio.ch.DevPollArrayWrapper.init(Native Method)
try to run it as root and see if that solves it, if it does, you have to figure out
what permissions to add to your user

Subject: WG: Tomcat 4 Clustering
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
