Windows 2012 R2 - NUMBER_DATA_BUFFERS not being used

NB 7.7.1

I have a RedHat master - with lto6 tape drives and a few Windows 2012 R2 media servers.

The NUMBER_DATA_BUFFERS and SIZE_DATA_BUFFERS - are set on the Red Hat master - /usr/openv/netbackup/db/config - and work great.

However - when we set the same values on the Windows 2012 R2 media servers - it will not use the values we specify - using same values as the RedHat master.

It keeps using the default 65536 and 12 values.

They are located in C:\program files\veritas\netbackup\db\config

NUMBER_DATA_BUFFERS

SIZE_DATA_BUFFERS

Did something change in NB 7.7.1 to adjust buffers in Windows media servers? The tuning guide still hasn't been updated for 7.7.
