Symptoms

Consider the following scenario:

  • You have a computer that is running Windows 7 or Windows Server 2008 R2.

  • You try to export to some circular files that are used by the Event Tracing for Windows (ETW) feature.

In this scenario, you cannot export to these files, and you receive the following error message:

out of memory

For example, consider the following scenario:

  • You run the following command to set the cluster log size to 512 megabytes (MB):

    cluster log /size:512

  • You run the following command to export the trace to a text file:

    cluster log /g

In this scenario, you receive the error message. Because of this issue, the memory usage of the Cprepsrv.exe process is high. Additionally, the computer stops responding because memory is insufficient.

Cause

This issue occurs because the ETW engine handles finalized files incorrectly.

When the ETW engine handles some circular files that have finalized and non-finalized files, the buffer count value becomes very large. However, this incorrect buffer count value is used to allocate memory. Therefore, you receive the error message that is mentioned in the "Symptoms" section.

Resolution
