title: BizTalk - Receive Port reading twice from DB
body: <p>My receive port is of sqlBinding and typed polling. It invokes a SP to fetch a record and based on filter condition the corresponding orchestration kicks off. The BizTalk group consists of 2 servers; thus 2 ReceiveHostInstances. If both the host instances are running -at some point the same request is being read twice - causing a duplicate at the receivers end. But, why is the reeive port reading it the same record more than once? The proc which reads the updates the record and updates it so that it wont be fecthed again. </p>
  
  <p>I observed this scenario while submitting 10 requests; receive port read 11 times and 11 orchestrations started.</p>
  
  <p>I tried the same (10 request) with one host (as in my Dev), the receive is showing 10 only. Any clues?</p>
