Remote procedure call service crashes on a computer that is running Windows Server 2003 SP2, Windows Vista, Windows Server 2008, Windows 7 or Windows Server 2008 R2

Not sure if this is the right fix? We've added this issue to our memory dump diagnostic which can confirm.

Symptoms

On a computer that is running Windows Server 2003 with Service Pack (SP2), Windows Vista, Windows Server 2008, Windows 7 or Windows Server 2008 R2, a Svchost.exe process that hosts the remote procedure call (RPC) service crashes. When this issue occurs, the following error message is logged in the Application log:

Cause

This error occurs because the remote procedure call service does not wait for all the asynchronous RPC calls to be returned before the service reallocates the structure. Because of this behavior, the asynchronous RPC calls access an incorrect reallocated address. Therefore, an access violation occurs, and the RPC service crashes.
