Source: MSExchange ADAccess
Version: 8.0
Symbolic Name: DSC_EVENT_LK_NOT_CACHED
Message: Process %1 (PID=%2). An attribute on object %3 is too large to be cached. Requested size was %4, maximum cacheable is %5. Performance may be degraded.
   
Explanation

This event indicates that an object attribute has exceeded the size limit for the DSAccess cache. Every time this object is requested, the server will have to contact the Active Directory instead of using the DSAccess cache. If the object is frequently needed, such as the server object, this condition may affect performance.
