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.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Microsoft Exchange 2000 Server service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English version of this fix should have the following file attributes or later:

Component: ESE



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server.



MORE INFORMATION
After you apply this fix, the split or merge logic in the ESE searches for incorrect page links in any of the pages that are involved in the split or merge operation; if the ESE finds an incorrect page link, the ESE errors out instead of looping continuously.
