Consider the following scenario. In Microsoft SQL Server 2000, you add a SQL Server Agent job, or you update a SQL Server Agent job. At the same time, another connection tries to delete a SQL Server Agent job. In this scenario, a deadlock occurs when the scheduled SQL Server Agent job that you add or that you update is running.

If you troubleshoot the deadlock by enabling trace flag 1204, you notice that the following error message is logged in the SQL Server error log file:

This problem occurs because SQL Server Agent does not schedule the SQL Server Agent job to run in the job cache. When SQL Server Agent runs the scheduled SQL Server Agent job, SQL Server Agent uses the sp_sqlagent_refresh_job stored procedure to update the job cache. If another connection tries to delete a SQL Server Agent job, a deadlock occurs.
