High CPU usage in non-Exchange process

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

  • The Microsoft® Exchange Server Analyzer Tool has a found a non-Exchange Server process that is currently using more than 20 percent of the server's available CPU. If a non-Exchange Server process is using more than 20 percent of the available CPU, an error is displayed.

  • It is recommended that your servers that run Exchange Server be dedicated to Exchange Server whenever possible and run as few applications or services as possible outside Exchange.

To correct this error
  • If another process causes most of the CPU use, try one of the following options:

    • Turn off the process and see whether the problem goes away.

    • Move that process to another server if you can.

    • Make sure that the process is configured correctly and look for any updates from Microsoft and the provider of the process that address this issue.

    • Uninstall the process if you do not need it.

  • If the process cannot be moved or fixed, the server should be rescaled to allow for the added load of the non-Exchange Server process. You should consider moving users to another Exchange server as part of this rescale.
