Assigning Additional Memory to the WMI Pool
Under certain circumstances, WMI may encounter a memory limit and need additional memory assigned to its memory pool.
To assign additional memory to the WMI pool:
1From the Windows Control Panel, restart the Windows Management Instrumentation service.
2To re-register all performance libraries with WMI, open a Windows command prompt and type winmgmt/resyncperf, then press Enter.
3Set the WMIHandlesPerHost value to 8192 (0x2000). For guidance, refer to http://blogs.technet.com/b/askperf/archive/2008/09/16/memory-and-handle-quotas-in-the-wmi-provider-serviceNew Link.aspx.
