Abstract
An embodiment includes sending, via a queue pair (QP) at a first endpoint, a message to a second endpoint. The embodiment also includes detecting an error state of the QP caused by a failure at a third endpoint that automatically halts messages via the QP. The embodiment includes determining that communication between the first and second endpoints via the QP is viable, and placing messages to the second endpoint in a separate queue from messages to an unreachable endpoint. The embodiment also includes re-establishing communications between the first and second endpoints via the QP, and polling the second endpoint for an indication of a delivered message. Any messages indicated as having already been delivered are removed from the queue before re-starting communications with the second endpoint.
