BizTalk SQL Server Job always fails after some hours

Question

We have BizTalk 2016 running on SQL Server 2016 AlwaysOn.

The SQL Server Agent Job MessageBox_Message_ManageRefCountLog_BizTalkMsgBoxDb is doing its thing but after some hours it fails. Sometimes 10 hours sometimes 90 hours or anything in between. I know, the job is designed to run forever and in a case of an error restarts itself within a minute. But I would like to know the actual error message for this failed job. The job history is not helpful because the job log entry is truncated.

A failover is not happening. The question is: WHY is this job failing and ultimately: how do I stop it from doing that?

---

I have set-up the extended monitoring of the failing step and it revealed, that the job failed because of a deadlock and it was chosen as the deadlock victim. So now is the question, why is there a deadlock? Is MessageBox_Message_ManageRefCountLog_BizTalkMsgBoxDb known for deadlock issues?

Answer 1

Check the documentation at Description of the SQL Server Agent Jobs in BizTalk Server , it says:

Important At first, the MessageBox_Message_ManageRefCountLog_BizTalkMsgBoxDb job status icon displays a status of Success. However, there will be no corresponding success entry in the job history . If one of the jobs in the MessageBox_Message_ManageRefCountLog_BizTalkMsgBoxDb job fails, a failure entry appears in the job history and the status icon displays a status of Failure. The job will always display a status of Failure after the first failure . To verify that the other BizTalk Server SQL Server Agent jobs run correctly, check the status of the other BizTalk Server SQL Server Agent jobs.

Hope this answer your question.
