BizTalk Server Question:

BizTalk server detects the potential for certain race conditions, which are ensured that all correlated messages are received by the same orchestration instance. The potentiality of these race conditions is detected by BizTalk server. These messages are treated as a 'convoy'. A convoy set is a group of correlation sets. All such subsequent messages which match the general subscription are evaluated against the convoy set, and the matched convoys are routed to an existing port.
