Error description
When running a task that creates and accesses large numbers of view private files in parallel in an IBM Rational ClearCase dynamic view, the ClearCase host may crash reporting an error in mvfs100x64.sys. The dump will report this as a "CACHE_MANAGER" dump.
Local fix
Disable the MVFS cache manager by setting the following registry value to 0: HKLM\system\Currentcontrolset\services\mvfs\Parameters\UseCacheM anager. Then reboot the host. This should eliminate the crash, but may degrade MVFS performance.
