Ok, I understand the exclusive queue now, but what do you mean by "aquired messages not accepted"? So if I don't use exclusive queue and heartbeat, does my client still have risk to be locked up? If so, under what condition?
Also does anyone know what does the following error mean? 2009-oct-31 10:17:49 error 172.27.34.201:9908(READY/error) channel error 157487219 on 172.27.34.201:9908-389(local): transport-busy: Channel 1 already attached to [email protected] 64-4e49-9bee-0538532fe261 (qpid/amqp_0_10/SessionHandler.cpp:150) (unresolved: 172.27.34.201:9908 172.27.34.202:13287 ) -----Original Message----- From: Carl Trieloff [mailto:[email protected]] Sent: 03 November 2009 17:07 To: Shan Wang Cc: [email protected] Subject: Re: An ill borker brings down the whole cluster Shan Wang wrote: > So even if heartbeat isn't set, the client can still failover to another > broker after some default timeout? > > Don't quite understand how could broker release resources based on heartbeat, > isn't heartbeat used by client to detect the outage of a broker?
