Subject Async Errors and duplex bridges
Date Fri, 26 Oct 2012 10:42:43 GMT
I'm seeing the following, repeatedly, in our logs (5.7.0):

2012-10-26 11:37:04,193 | WARN  | Async error occurred:

BrokerService[hub] Task-64
org.apache.activemq.transport.TransportDisposedIOException: Peer
(vm://hub#11) disposed.

Our topology has our hub in our office connected via ADSL to three remote
brokers each of which have various services on them. Each isolated broker
has PHP scripts connecting via PECL Stomp.

I'm wondering if there might be a timing problem due to temporary bandwidth
restrictions perhaps? Pure speculation as I have little else to go by...

Thanks,

James
