Thanks @scutters .
That works for PinBot and JackBot
And think find the Gremlin in my system.
for some reasons, when PBX closes the tables (or kill it, not sure what method PBX is using), I noticed NVrams didn't save.
I thought it was a PBX timing, but discovered that windows VSS (Volume Shadow copy Service) was trying to access the file as well.
This gave an access denied, and the nvram wasn't saved at all
Event ID 8194 generated a lot on my machine :
(Sorry for my Dutch events)
I completely stopped VSS on my computer to have a correct save of the nvram Note: By disabling this feature you’ll also disable System Restore, so keep that in mind.
Here's a quick tutorial to stop VSS if you encounter the same issue :
Press Windows Key + S and enter advanced system. Now select View advanced system settings.
Navigate to the System Protection tab and select the drive that has protection enabled. Click the Configure button.
Select Disable system protection. Now click Apply and OK to save changes.
Note: By disabling this feature you’ll also disable System Restore, so keep that in mind.
Alternatively, you can disable Volume Shadow Copy service by doing the following:
Press Windows Key + R. Enter services.msc and press Enter or click OK.
Locate the Volume Shadow Copy and double-click it.
Set the Startup type to Disabled. If the service is running, click the Stop button to disable it. Lastly, click Apply and OK to save changes.
