[1151441] - JON server was unexpectedly stopped after ~ 1 day
Improve log message relevant to the reported failure.  I think this issue
is due to a change of IP, or some other change to the result of
InetAddress.getLocalHost().getCanonicalHostName(), which is the default
value for the server if it is not explicitly set in rhq.server.high-availability.name.
