Hi Dushan/Chanaka,
The log message is added after creating a new subscription as below and it
is not just increasing a number.
Subscription subscription =
SubscriptionFactoryImpl.INSTANCE.createSubscription(_channelId, _session,
tag, acks, filters, noLocal, _creditManager);
return new SubscriptionImpl.AckSubscription(channel, protocolSession,
consumerTag, filters, noLocal, creditManager, clientMethod, recordMethod);
What is the ESB version you are observing this and is this whole log is
seen at the server start up? If this is with ESB 4.8 MS/MP implementation,
I also tried and noticed a similar scenario where i have a MP named
RequestProcessor which listens on queue, request_queue, which is bound to
MS, RequestStore. If i add only a new MesageStore (say ResponseStore) i can
see the following log.
[2013-09-17 13:49:37,902] INFO
{org.wso2.andes.server.cassandra.DefaultClusteringEnabledSubscriptionManager}
- Removing Subscription 2 from queue request_queue
[2013-09-17 13:49:38,639] INFO
{org.wso2.andes.server.cassandra.DefaultClusteringEnabledSubscriptionManager}
- Binding Subscription 3 to queue request_queue
The again i edited a name of a proxy service in my ESB pack and saved the
configuration back, and again there were two similar logs for removing and
binding existing MB subscription. Therefore i think MS/MP implementation is
written to create a new Subscription every time when synapse configuration
is changed?

When adding the queue dynamically, it is true that a new subscription is
created. However in that case subscription is created and closed a single
time and it happens within few seconds. but when seen the logs it seems
removing of subscription has happened after around 1 minute. Therefore i
feel this is not what has happened here.
Thanks!
