Abstract
A method, computer program product, and computer system are provided. An adjunct processor receives an indication to reset a message queue. The reset removes all messages from the message queue on the adjunct processor. The reset is in response to a hardware failure or an external manual operation. An operation to enqueue a message to the message queue is received. Based on completing a successful enqueue operation, the adjunct processor sets a status that includes an indication that the enqueue operation is a first operation following the reset. A requestor receives the indication of the first operation. Based on the internal count of pending messages being greater than one, the requestor requeues to the adjunct processor, the message requests, except for the first message, having outstanding replies, and resets the indication of the first enqueue operation upon the requeuing of the message requests being complete.
