Bug #: 310 (SQL Hotfix)
Microsoft distributes Microsoft SQL Server 2000 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2000 fix release.
This article describes the following about this hotfix release:
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:
Deadlock encountered .... Printing deadlock information …
Date Time SPID Node:1
Date Time SPID SPID: 77 ECID: 0 Statement Type: DELETE Line #: 124
Date Time SPID Input Buf: Language Event: EXECUTE msdb.dbo.sp_delete_job @job_id = 0x9D8193BA4AB3E84381F15C1701991638

Date Time SPID ResType:LockOwner Stype:'OR' Mode: S SPID:52 ECID:0 Ec:(0x36829558) Value:0x5b7084a0 Cost:(0/0)
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.
