SYMPTOMS

The following event may be displayed in the Windows NT Event Viewer Application log of the Exchange Server computer:

   Event:1160
   Source:MSExchangeIS
   Type:Error
   Category:General
   Description:
   Database resource failure error -1011 occurred in function
   JTAB_BASE::EcPrepareUpdate while accessing the database.

CAUSE

This error may be reported if the Performance Optimizer is run and, in the Memory Usage properties, the value for Limit Memory Usage to <value>MB is set to something other than zero (0).

Because this value sets the limit on how much memory all of Microsoft Exchange has to use, the lower the value, the more likely this error message is to be displayed. If this value is set too low, for example, to 25, the services will run, but after a short time the server's performance will degrade. Shutting down the service will take a long time as well.

RESOLUTION

To correct this problem, run Microsoft Exchange Performance Optimizer and reset the <value> to zero (0).

MORE INFORMATION

Database resource failure error -1011 occurred in function
