Citrix Provisioning Services 6.1 hotfix #18: RAM Cache alert

Finally Citrix made it possible to trigger a alert in the Windows event log of the target device when the RAM cache usage exceeds a set treshold! Details:

With this fix, the target device reports errors to the Windows system event log when the usage of RAM cache exceeds a set threshold (default 90%).
After that warning, every 2% increase in usage triggers the error as well.
This error report will also be redirected to the server side “StreamProcess.log” as a warning message if the log is enabled.

To enable the fix, you must create the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BNIStack\Parameters
Name: WcWarningPercent
Type: DWORD
Value:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BNIStack\Parameters
Name: WcWarningIncrement
Type: DWORD
Value:

[From CPVS61018][#LA3382]
