No, that can't be it
did you try it?
Yes, I did try that.
With the bind attribute, a SINGLE tomcat binds to the correct NIC and
the cluster works perfectly. It's only when we have TWO tomcats both
on the same machine that we have the problem.
Without the bind attribute, Tomcat binds to the wrong NIC which
prevents the other nodes from getting the multicast packets.
I could experiment with another windows box to see if I can run 2
tomcats without the bind attribute. (I can't do that on the machine
that's experiencing the prob because it's a production box.) But even
if that works, we stuck, because we have to use the 2nd NIC for
clustering.
Could it be that a socket is not being closed?
Thanks!
