Re: java.net.NoRouteToHostException: No route to host: connect busy loop in JoinManager

Hi,
We seem to observe the same issue as the issue Greg encountered before.
It is very easy to reproduce.  Unplug the network cable and the cpu shoot
up to 100%.
Do we know what is the status of this issue right now?
Would appreciate any help on this issue.  Thank you very much.


The log printout shows many NoRouteToHostException in JoinManager in a
very short time.

After inserting some log into the RetryTask and TaskManager, it seems that
there are many RetryTask running.  Those RetryTask are either
JoinManager$ProxyRegTask or LookupLocatorDiscovery$DiscoveryTask.

sorry the line number on RetryTask and TaskManager might be incorrect due
to some log statements inserted in there to print stack trace.
