| Description | Error 0xfffffbd3 occurred on message 1-EB1F8B1 during a background cleanup. |
| Event Information | According to Microsoft: CAUSE: This problem can occur if the information store sets the Max Open Tables and Preferred Max Open Tables values (which regulate the number of Open Tables in the JET database) incorrectly when the information store starts. The calculation to set these values is dependent upon many things and is very complex. The Preferred Max Open Tables value is always set lower than the Max Open Tables value. If the information store reaches the value set by the Preferred Max Open Tables value, JET starts a scan to try to find resources that can be used to comply with more requests for open tables. This scan repeats aggressively, which results in the degradation of the information store process. RESOLUTION: A supported hotfix is now available from Microsoft, but it is only intended to correct the problem.Only apply it to systems that are experiencing this specific problem.To resolve this problem in Exchange Server 5.5, the Preferred Max Open Tables value must be set equal to the Max Open Tables value when the Information Store service starts. This key must be manually added and set to any value other than zero so that the Information Store service automatically sets the Preferred Max Open Tables value equal to the Max Open Tables value. |
