Hi Vinod, I have found the potential problem: one instance of the class *org.wso2.carbon.business.messaging.hl7.common.HL7ProcessingContext* is shared over multiple threads request for the same proxy and the blockingQueue *applicationResponses *could contains all the responses(in any order based on server response time). When *handleApplicationACK *is called from each thread this method return *the first *response in the queue(if available, otherwise the thread wait for any), without making sure it is the answer(ACK) associated with the current message(*hl7Msg *parameter). I have observed that the order of the *applicationResponses *queue could be different of the order of the waiting thread. This causes the wrong ACK to be sent to the sender.
How to we proceed to the bug fix? Many thanks Marco P.S.: I have already opened this issue: https://github.com/wso2/carbon-mediation/issues/928 *Marco Sessa* *Software Analyst / Developer* CSP S.p.A.
