Event ID 4690 — COM+ General Functionality

Updated: February 22, 2008

Applies To: Windows Server 2008

red

COM+ applications use Microsoft Component Object Model (COM) technology in Microsoft Windows operating systems to communicate and take advantage of Windows services. COM technologies include COM+, DCOM, and ActiveX Controls.

Event Details

Product: Windows Operating System
ID: 4690
Source: Microsoft-Windows-Complus
Version: 6.0
Symbolic Name: IDS_COMSVCS_RESOURCE_ERROR
Message: The run-time environment has detected the absence of a critical resource and has caused the process that hosted it to terminate. %1%0

Resolve

Correct the low-resource condition

The event message indicates that there is a problem in the COM + service runtime. There is not enough information available in the event message to provide a definitive recommendation to resolve the problem. In the meantime:

  • Check the system for a low-resource condition.
  • You can resolve a low-resource condition by increasing the page file size. A page file is a hidden file or files on the hard disk that the operating system uses to hold parts of programs and data files that do not fit in memory. Virtual memory comprises the paging file and physical memory or random access memory (RAM). Windows moves data from the paging file to memory as needed, and it moves data from memory to the paging file to make room for new data. Increasing the page file size usually does not require a restart of the computer.
  • You may be able to resolve a low-resource condition by ending unnecessary processes to free memory resources. Be careful when you end a process. If you end a process that is associated with an open program, the program will close and you will lose unsaved data. If you end a process that is associated with a system service, part of the system might not function properly.

If you continue to get this error, note any details in the event message, and then contact Microsoft Customer Service and Support (CSS). For information about how to contact CSS, see Enterprise Support (http://go.microsoft.com/fwlink/?LinkId=52267).

To perform these procedures, you must have membership in Administrators, or you must have been delegated the appropriate authority.

Check the system for a low-resource condition

To check the system for a low-resource condition:

  1. Right-click the taskbar, and then click Task Manager.
  2. Click the Performance tab, and then look for the amount of physical memory used under Memory and Physical Memory Usage History. If the amount of memory used is high, consider increasing the size of the page file.

Increase the size of the page file

To increase the size of the page file:

  1. Click Start, click Control Panel, and then double-click System.
  2. Under Tasks, click Advanced System Settings. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. Click the Advanced tab. Under Performance, click Settings.
  4. In the Performance Options dialog box, click the Advanced tab.
  5. Under Virtual Memory, click Change.
  6. Clear the Automatically manage paging file size for all drives check box.
  7. Under Drive [Volume Label], click the drive that contains the paging file that you want to change.
  8. Click Custom size, type a new size in megabytes in the Initial size (MB) or Maximum size (MB) box, click Set, and then click OK.

Free memory resources to end a process

To free memory resources to end a process:

  1. Right-click the taskbar, and then click Task Manager.
  2. Click the Processes tab, and then click Show processes from all users (at the bottom of the tab). If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. Be careful when you end a process. If you end a process that is associated with an open program, the program will close and you will lose unsaved data. If you end a process that is associated with a system service, part of the system might not function properly.

    Try to identify processes that are leaking memory by looking for processes with unusually high memory consumption. Select a process to end, and then click End Process. For more information about how to identify a process that is leaking memory, see Using Performance Monitor to Identify a Pool Leak (http://go.microsoft.com/fwlink/?LinkId=105512).

Verify

You can verify that your COM+ application is installed and working properly by using the Component Services administrative tool.

To perform these procedures, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To open Component Services and verify that your application is installed:

  1. Click Start, and then click Run.
  2. Type comexp.msc, and then click OK. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. To locate your application, click Component Services, click Computers, click My Computer, and then click COM+ Applications.

In addition, you can verify that the COM+ operating system component is installed and working properly.

To verify that COM+ is working properly:

  1. In the console tree of Component Services, click Services (Local).
  2. Scroll through the list of service names to find the following services: COM+ Event System (optional), COM+ System Application, DCOM Server Process Launcher, and Remote Procedure Call (RPC).
  3. Confirm that the status of each service is Started.
