Usage Scenarios for Extended Events?
Extended Events are the future as Microsoft are not doing any investment in SQL profiler area. You should use Extended Events to track down the root cause of orphaned-transactions. This is the quickest way to figure out whats causing this problem in a live system.

Troubleshooting Orphaned Transactions?

In SQL Server we have transactions. In order to mark any transaction as as an orphaned, distributed transaction SPID, SQL Server changes the SPID from a positive number to -2.  This only problem is the SPID may still be holding on to resources (usually table, page or row locks), and blocking other SPIDs which want to access that database object.
There could be number of reasons why SQL marked any transaction as Orphaned. One of the reason could be Phantoms.
