We're running JBoss 3.2.6 in a clustered environment with two nodes. First
issue is that I see an exception in the log when one of the nodes starts, but
no problem with the other node. The log looks like this:
2006-05-17 10:47:48,911 INFO

At the start of the log excerpt I pasted above, you can see that it appears to
have recognized the other node, so I'm not sure if the exception is relevant,
but it does concern me. The configuration appears identical on both servers, so
I'm not sure why this happens on one and not the other.
The other issue is an exception that appears about once every minute in the
logs on both nodes. Here is the exception:

Any thoughts on this? Upgrading JBoss is not an immediate option for us,
although we will consider it in the hopefully not-too-distant future.
