  Q256986 Description of the Microsoft Windows Registry

SYMPTOMS
========

You may see a spike in Store.exe in Performance Monitor under the Page File
Bytes counter. Store.exe continues to rise until resources are exhausted. CPU
utilization is extemely high, as seen in the DPC Queued/sec counter, and you may
be unable to log on to the console. All appearances point to a memory leak in
Exchange Server Store.exe as Pool Nonpaged Bytes mirror the trend seen in the
above counters.

CAUSE
=====

This behavior can occur if you are using ArcServe Agent for Exchange Server
Backup. ArcServe may be referencing the wrong memory allocation.

RESOLUTION
==========

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.

To resolve this issue, use the following steps:

1. Start Registry Editor (Regedt32.exe).

2. Locate the following registry key:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DBAGENT\Type

3. On the Edit menu, click DWORD, type "10" (without the quotation marks)
  (hexadecimal value), and then click OK.

4. Quit Registry Editor.
