Negative spid in SQL SERVER.

No comments

When you have a negative spid ( ex: -2) in SQL SERVER, it is related with Microsoft Distributed Transaction Coordinator (MSDTC).

You can do it from 2 different ways:

Outside SQL SERVER, in component services > DTC > Transactions > rollback the transaction.


select distinct req_transactionUOW from syslockinfo , ignore the 000000’s

kill ‘GUID’ . ( ghost/orphaned transaction ).
