Tracking a processor instruction is provided to limit a speculative mis-prediction. A non-speculative read set indication and/or write set indication are maintained for a transaction. In addition, a queue(s) of at least one address corresponding to a speculatively executed instruction is maintained. For a received request from a remote processor, a transaction resolution process takes place, and a resolution is performed if an address match in the queue is detected. The resolution includes to hold a response to the receive request until the speculative instruction is committed or flushed.
