multiple ReceiptAck

one of the particular process model is generating multiple ReceiptAck.
This is a one action responder process model.
partner sends in pip, process model is triggered all the steps are completed successfully.
But partner is receiving multiple receiptacknowledgement messages

any solution

  1. is that new model generated or working model?
  2. Send Receipt acknowledment retried multiple times?

this was a new model. no, partner was receiving 4 receiptack.
basically second receiptack is sent even when first one was sucessfull

any responses for this

is that possible can you attach model here to debug (export ur model from modeler).
