Transport exception in ActiveMQ 4.1.0 logs at debug level

[aakture <al...@tidalsoft.com>]

I was trouble shooting a transport failure error message in my client, and
had turned up the ActiveMQ log to DEBUG. I happened to see the following
message logged at debug in the ActiveMQ log, although I was not able to
reproduce the exception I was seeing in my client during this same test run.
Is this something I need to worry about? It only happened over a few minute
period during a several hour test run, and didn't happen again. Any ideas
what could cause it?
