SQL Server Service Broker Deadlock
<p>I'm investigating a process that I did not build.  It uses the service broker to create a queue of contacts that then need an action against them.</p>

<p>There is then a handler that receives 10k records and passes them to a stored procedure to process.</p>

<p>What happens if that final process fails for a deadlock with no error handling?  Do these go back into the queue?  If not what would I need to do to get them to go back into the queue?</p>
