Comment 1 for bug 1044298

I've found out that there is a problem with rpc.call which should run delete method.

StackTrace:

here is error which I've found in syslog. I saw also information about amqp timeout. Why rabbit isn't working properly? I can see services on multiple nodes, so rabbit should works, but while I'm "deleting/terminating" instance I see timeout and this stacktrace...
