FIX: Application Hangs When Inserting Records Into Access 97 Database


View products that this article applies to.

This article was previously published under Q254760

↑ Back to the top


Symptoms

When an application that uses Microsoft Jet database engine 4.0 is rapidly inserting records into a database file that is in Access 97 format, the application may stop responding, or hang, after some random amount of time and the application has to be terminated abnormally. This only occurs when the database file is an Access 97 (Jet 3.51) database format, it does not occur when the database is a Jet 4.0 database.

Cause

When Jet 4.0 needs to access a Jet 3.51 database, it loads an additional file to read and interpret the Jet 3.51 database format. This file is the Jet 3.51 ISAM driver Msrd3x40.dll. The hang occurs when this file is in use.

The hang in Msrd3x40.dll is caused by a critical section deadlock, which happens when one thread is preparing to write modified memory pages to disk while another thread is committing data.
