Hi Dhiraj,
please refer the webMethods MQ Adapter Users and Installation Guide for further informations.
As the synchronous notification waits for the flow service to complete before invoking the next one, you will have to switch to asynchronous notifications which will publish the received messages to Messaging component (either Broker or UM) and you can then use a concurrent trigger to invoke the flow service. But be aware that the data can overlap in this case when later invocation will be completing faster than an earlier invocation.
Make sure that you have latest Fixes for MQ Adapter applied which should be MQS_6.5_Fix48 or newer.
Remember to check the version of the MQSeries jars against the version of the MQSeries Server, the provider of the MQSeries instance can help you here.
Regards,
Holger
