SYMPTOMS

An incorrect page link in the Extensible Storage Engine (ESE) database may cause online defragmentation to loop continuously.

CAUSE

This problem can occur if the latching logic for merges processes an incorrect page link as a transient error (errBTMergeNotSynchronous). An incorrect page link is caused by a split or merge operation on an adjacent page.
