> Hello,
> There's a problem with the FailoverTransport not shutting down cleanly.  It appears that
it shuts down it's underlying transport, e.g. TcpTransport, but then doesn't disable it's
handleTransportFailure thread, which then complains that the underlying transport has gone
away, and tries to restart it again.
> Looking at the code in FailoverTransport.java, there appears to be a simple fix, to check
the 'started' variable in the method 'handleTransportFailure' before logging a warning and
trying to restart the underlying transport.
> Here's a log snippet that demonstrates the problem:
> DEBUG [2008-02-04 03:44:05,752] thread:main                                FailoverTransport
