↑ Back to the top

Symptoms

The information store may not start (even with an empty Mdbdata folder) and the following event ID may be logged:
Event ID: 188
Event Type: Error
Event Source: ESE97
Event Category: System Parameter Settings
Description:
MSExchangeIS (1956) System parameter stop clean flush threshold (1962) is less than start clean flush threshold (3270).

↑ Back to the top

Cause

This issue can occur if the Buffer Threshold Low Percent registry key is missing or has an incorrect value (too high).

↑ Back to the top

Resolution

To resolve this issue, make sure that the Buffer Threshold Low Percent key exists and has a value that is equal to or less than the Buffer Threshold High Percent value.

Exchange Performance Optimizer (Perfwiz) adds two registry keys: the Buffer Threshold Low Percent key and the Buffer Threshold High Percent key. Both keys may not exist; this does not cause any issues. However, if one of these keys exists, the other key must also exist.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

These keys are located under the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Service\MsExchangeIs\ParameterSystem
The default setting for both keys is REG_DWORD: 0x3.
