Re: [jgroups-users] jgroups - callRemoteMethodsWithFuture blocks on coordinator crash

This is the expected behavior.

Consider a similar case where you're making a blocking RPC on all 
cluster members.

If one of the members crash during the RPC and is thus not able to send 
a response, the caller will block until either a timeout occurs (if the 
call is time-bounded) or failure detection kicks in and marks the 
response of the crashed member as faulty, so that the call can return.

You could try bounding your blocking RPCs or make them async if the app 
allows that...
