Nonpaged pool memory leak mfeavfk.sys on multiple windows server 2012 R2

We have ENS 10.6.1.1068 installed across 600 windows servers. We found 25% of servers Non-paged pool memory leaks poolmon tag with MFe0 which points to mfeavfk.sys consuming high memory. Gradually server hungs due runs out of memory and reboot is carried with no other options. 

Task manager shows:

When you start pool mon with /p switch for non paged and the sort by bytes (b)  .. you can see the usage quite clearly the MFeS drivers taking the memory

Rammap shows

As per the known issues KB82450 please note I dont have any debug logging turned. 

After uninstall the ENS from the problematic server and reboot the server's memory seems to be stable. However we can't run production system with AV. Anyone with ENS 10.6.1 expereience this issue?
