SYMPTOMS

Consider the following scenario:
  • You install Microsoft SQL Server 2008 R2 or Microsoft SQL Server 2008 on a computer.
  • You configure Peer-to-Peer Transactional Replication and then enable conflict detection on a table.
  • Later, you disable conflict detection for the Peer-to-Peer Transactional Replication.
  • You update the statistics of the table.

In this scenario, the update fails, and you receive the following error message:
Msg 0, Level 11, State 0, Line 0

A severe error occurred on the current command. The results, if any, should be discarded.
Additionally, an access violation exception occurs, and a mini-dump file is generated in the SQL Server error log folder.

CAUSE

This issue occurs because the database engine is trying to load dangling statistics. When P2P conflict detection is enabled, an MDColumnIdP2pCdId system column is added to the base index rowset of the table. Replication-related queries may create statistics on the system column automatically. When P2P conflict detection is disabled, the system column is removed from the table. However, the corresponding statistics remain. Therefore, updating statistics causes the access violation exception to occur because the statistics cannot be added to the table.
