Message Text

Error 3617 is raised when a query that is in the middle of execution gets canceled by the

application or by a user, or the connection is broken. This query cancellation from the

application causes an Attention event to occur in the Database Engine. The Attention event is a

event that registers the client application’s request to terminate query execution.

You can trace an Attention event on the SQL Server side by using the Extended Events or SQL

Trace

Attention Event Class. Attentions show up internally as error 3617.

Attention (query cancellation) is among the top most common

TDS event

handled by SQL

Server. When a query cancellation request arrives, the attention bit is set for the

session/request. As the session processes yield points, the attention is picked up and honored.

For some more information on attentions and how they interplay with other components see
