could be something totally different.
Application creates multiple Connection/Channel pairs and each is assigned
its own Consumer instance.
We have a single consumer per channel per connection.

Here's a snippet of code from Consumer.handleDelivery() method modified to
remove business specific information.
But this is the gist of what happens when a message is received.

    public final void handleDelivery(String consumerTag, Envelope envelope,
            BasicProperties properties, byte[] body) throws IOException {

        boolean failed = false;
        Throwable failureReason = null;
        try {
            // create a delivery for the client
            delivery = createDelivery(consumerTag, body, envelope,
properties);
            // deliver to client
            deliveryHandler.handleDelivery(delivery);
        } catch (Throwable e) {
            // client had a problem handling/processing delivery
            failed = true;
            failureReason = e;
            log.error("Client failed while handling delivery. "
                    + e.getMessage(), e);
        } finally {
            if (failed) {
                handleFailedDelivery(
                        failureReason, body, properties);
            } else {
                try {
                    acknowledge(envelope.getDeliveryTag());
                } catch (Exception e) {
                    notifyClient(e);
                }
            }
        }
    }

Envelope object that is handed to the method as an argument stays method
local.
Our application is connecting to the cluster through a netscaler VIP.

We have not seen this problem when consuming from a local cluster with the
same application.

Any help or pointer in the right direction is appreciated.

Thanks,
Vineet
