Internal cache error. Hash table value is incorrect. Restart the Microsoft Exchange Active Directory Topology service or restart the server. Review System log for hardware errors. |
Explanation
This Error event indicates that a hash table iterator is invalid. A hash table stores frequently accessed and fast changing information in the memory cache. The records are added and deleted dynamically to maintain optimal memory use. An iterator is used to move through the records of a hash table. If the iterator is invalid, it cannot use a hash table.
This event may be caused by internal memory issues.
User Action
To resolve this error, do one or more of the following:
Restart the Active Directory® topology service. If the error persists, restart the Exchange server that logged this event.
Review the System log for hardware issues.
Verify that the version of DSAccess.dll matches the version of its companion DLLs. For more information, see Exchange Server 2003 Active Directory Integration.
