FIX: The BizTalk Server MessageBox database grows very large because records are not cleared in the EqualsPredicate2ndPass table in BizTalk Server 2010

View products that this article applies to.

Symptoms

Consider the following scenario:
  • You run BizTalk orchestrations that result in instance subscriptions in Microsoft BizTalk Server 2010.
  • When the instances of the orchestrations are processed, records are generated in the EqualsPredicate2ndPass table.

In this scenario, some of these records are under heavy load, and the bts_PurgeSubscription stored procedure does not clear records in the EqualsPredicate2ndPass table. This causes the BizTalk Server MessageBox database (BizTalkMsgBoxDb) to grow very large.

Cause

This issue occurs because the EqualsPredicates2ndPass table does not have same indexes as other predicates tables. Therefore, an index scan is used instead of seek when delete statements are run. When this occurs, some records are not cleared under heavy load.
