tao commented on AMQ-641:
-------------------------

I see.
But not blocked the method transfer,It can throw errors or return false.
You can see the log,why sometimes throw errors but not return,the application is stoped.
I used others jms server, them always throw errors when net or Server not work.

In the AMQ 4.0 set the jms client  with "java.naming.provider.url = failover:tcp://128.64.7.27:61616?useAsyncSend=true ",the result is too bad.
