SYMPTOMS

In Microsoft BizTalk Server 2006, you may encounter the following symptoms:
  • The CPU usage remains high for a long time on a computer that is running Microsoft SQL Server. During this time, the bts_FindSubscription stored procedure executes many logical reads.
  • The PurgeSubscriptionsJob_BizTalkMsgBoxDb SQL Server Agent job takes longer than usual to run.

CAUSE

This problem occurs because some query plans that the SQL Server query optimizer chooses are incorrect.

RESOLUTION

Hotfix information

A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing this specific problem. This hotfix might receive additional testing.
