Hi Devs,
I am working with a Stratos deployment these days. In our deployment, we
are using WSO2 Message Broker as the message broker. There I see the
following log getting printed very frequently (every second).
TID: [0] [MB] [2014-05-05 08:31:52,352] INFO
{org.wso2.andes.server.exchange.TopicExchange} - Message routing key: ping
No routes. {org.wso2.andes.server.exchange.TopicExchange}
TID: [0] [MB] [2014-05-05 08:31:52,352] WARN
{org.wso2.andes.server.AMQChannel} - MESSAGE DISCARDED: No routes for
message - Message[(HC:449176483 ID:366318838955900928 Ref:0)]:
366318838955900928; ref count: 0 {org.wso2.andes.server.AMQChannel}
TID: [0] [MB] [2014-05-05 08:31:52,621] INFO
{org.wso2.andes.server.exchange.TopicExchange} - Message routing key: ping

TID: [0] [MB] [2014-05-05 08:31:52,621] WARN
{org.wso2.andes.server.AMQChannel} - MESSAGE DISCARDED: No routes for
message - Message[(HC:1522105342 ID:366318839026417664 Ref:0)]:
366318839026417664; ref count: 0 {org.wso2.andes.server.AMQChannel}
I came to know that this is due to a mechanism used to check whether the
Message Broker (MB) is alive. i.e. subscribers publish an event to this
"ping" topic to see whether the MB is alive, but no one is consuming it.
Thats why the above log is getting printed.
Since no one is consuming this messages, is it possible that MB gets loaded
with this message and cause problems?
Regards,
Amila.
