AppLocker on Server 2012 R2 causing memory spike in depedent processes

    Question

  • Hello,

    I am running AppLocker on my Windows Server 2012 R2 machines, and after several hours of run time, two of the Application Identity service's dependent services using SVCHOST will spike their memory utilization, in some cases to over 2-3 GB each.  The processes "families" as they are grouped in the task manager are the "Service Host: Remote Procedure Call" and "Service Host: DCOM Server Process Launcher" - as I said, these are the dependencies of the Application Identity service that AppLocker uses to enforce the defined application control policies.

    Has anyone seen this before or have any ideas what could be causing this?  I have used AppLocker in the same manner with the same number of rules in Server 2008 R2 with no issues like this.  The problem also doesn't occur on the Windows 7 workstations which also run AppLocker.

    Is there a memory leak in the Application Identify service somewhere?

    Many thanks in advance.
