Microsoft Exchange was unable to initialize the Content Filter agent. It could not allocate sufficient memory for an internal buffer. Increase the available memory and restart the Microsoft Exchange Transport service. Details: %1

This Error event indicates that the Content Filter agent could not start because of insufficient memory. Specifically, there is not enough physical memory installed on the server to support all the applications that are running on the server.

To resolve this error, follow one or more of these steps:

• Reduce the number of applications that are running on the server.

• Restart the Microsoft Exchange Transport service.

• Add more physical memory to the server.

If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. Go to the Toolbox node of the Exchange Management Console to run these tools now. For more information about these tools, see Toolbox in the Exchange Server 2007 Help.
