XADM: JET Asserts on Heavily Used Multivalued Columns in the DS (156399)
The information in this article applies to:
- Microsoft Exchange Server 4.0
This article was previously published under Q156399 SYMPTOMS
When performing an operation in the directory (for example, adding
connectors, setting up replication, and so on) the JET may produce an
assertion (if running the debug build of Edb.dll) or possibly Dr. Watson
(if running the retail version). The assertion looks similar to the
following:
Jet Assertion Failure
Rel. 1416.0, File bm.c, Line 1218
(pfucbldx->ssib.pbf)->cWaitLatch > 0 && (pfucbldx->ssi.pbf)->cPin > 0 &&
(pfucbldx0>ssib.pbf)->ppibWaitLatch == (pbmfix->ppib)
PID: 416, TID: 224
CAUSE
During the expunge of a back link, JET deletes the old index item and
inserts another. While inserting another item, it causes another split on
the index and a move of some items also belonging to this cleanup. Because
the new page is not wait latched, it asserts. This happens only on indexes
of multivalue columns that the DS just added and uses heavily.
WORKAROUND
To work around this problem, obtain the hotfix mentioned below. With the
hotfix, JET aborts the cleanup (expunging) and retries it when it realizes
that some items were moved.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 4.0.
This problem was corrected in the latest Microsoft Exchange 4.0 U.S.
Service Pack. For information on obtaining the service pack, query on the
