It is possible that sql jobs are “hanging” in a suspended state. The SQL statements below will give you an indication on what the job is waiting.
The first SQL statement will create a small stored procedure in the master database, which can be called by “exec sp_check_state”.
The second sql satement won’t create any stored procedure.
use master
go
CREATE PROCEDURE [dbo].[sp_check_state]
