- Microsoft Exchange 2000 Server
This article was previously published under Q292305 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.
