Windows Server 2003 RTM

Windows Server 2003 Service Pack 1

Windows Server 2003 Service Pack 2

In the System event log, you might notice the following information:

Type: Information
Date: MM/DD/YYYY
Time: HH:MM:SS
Event ID: 26
Source: Application Popup
User: N/A
Computer: <Computer Name>
Details:
Application popup: Windows - Low On Registry Space : The system has reached the maximum size allowed for
the system part of the registry.
Additional storage requests will be ignored.

 

The way that I would start troubleshooting is the following:

1) In Perfmon, you might want to do the following:

Add System > % Registry Quota In Use > __________

Check to see what the maximum value it is.

Add Memory > Pool Paged Bytes > ___________

Check to see what the maximum value it is.

2) Check the sizes of the registry hives in:

C:\windows\system32\config

Security ____ MB

Software ____ MB

System ____ MB

Default ____ MB

C:\Documents and Settings\

Default User ____ MB

LocalService ____ MB

NetworkService ____ MB

User Profiles # ____

Each individual User Profile sizes ____ MB (Sometimes the median and biggest size can be enough).

3) Please make sure that you don’t have the following registry key set:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control

RegistrySizeLimit

124594 Understanding and configuring Registry Size Limit (RSL)

http://support.microsoft.com/?id=124594

4) If you don’t have the registry key set, install the latest UPHClean in http://blogs.technet.com/uphclean/ .

i.e.

32-bit UPHClean v2.0 build 2.0.49.0 (beta)

http://blogs.technet.com/uphclean/pages/uphclean-v2-0-beta-build-2-0-49-0-for-32-bit-platform-operating-system.aspx

After installing UPHClean, set the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UPHClean\Parameters
SHARING_VIOLATION_REMAP (dword) 1 (hex)

Stop and Restart the UPHClean Service.

5)  If you still have problems, the information that you gathered in step 2 might guide you to an application or service or driver that is not unloading the registry keys.

 

Hopefully this will help you narrow down the cause of the warning.

  • OK So this message is still occurring with the uhpclean installed on sbs 2003 r2 32bit 4gb ram.

    % Registry Quota In Use is constantly 93.285

    Pool Paged bytes are max 236601344

    Registry: security 76kb; default 512kb; system 4608kb; software 151,808kb

    This is not a terminal server. User profiles are v. small. Don't have registry key set for regsizelimit.

    Any further ideas how to proceed to finding what application or service or driver is not unloading the registry keys?

  • I have the same issue in Windows XP. How can I solve it ? the problem appears at startup. the warning window belongs to csrss.exe.

    download and install UPHClean. This service works in XP, too.
