If a record is locked when Microsoft Jet attempts to update it during a synchronization, Microsoft Jet retries the update several times. If the record remains locked after repeated attempts, the synchronization fails and Microsoft Jet records an error in the MSysErrors system table. Although this type of error is exceedingly rare, it might occur in certain multiuser applications. Errors caused by locked records can be ignored because Microsoft Jet will again try to update the record during the next synchronization. Because it is unlikely that the same record will be locked during the next synchronization, the record is updated and the error is removed from the MSysErrors table.
