I am seeing a strange Win2012R2 BSOD.
We have a WFP driver to inspect inbound/outbound traffic.
However this intermittent problem is seen only on Win2012R2 and even after applying all the correct symbols I am not able to resolve the call stack which leads to this BSOD.

According to trap frame analysis - the 0xffffe001`a80038ca is the faulting address and it has no Execute permissions.

2: kd> !pte 0xffffe001`a80038ca
VA ffffe001a80038ca
contains 000000000054D863 contains 000000000054C863 contains 000000000D7E3863 contains 80000001339F1963
pfn 54d ---DA--KWEV pfn 54c ---DA--KWEV pfn d7e3 ---DA--KWEV pfn 1339f1 -G-DA--KW-V

This address range specified for 0xffffe001a80038ca does not fall in the range of any loaded module. also when the addresses 0xffffe001a84e7e65, 0xb3b74bdee4453415, 0xb3b74bdee4453415 are unassembled they seem strange and I am not sure why instructions at 0xffffe001`a80038ca are being executed.

I don't have access to private symbols.

Can anyone please tell me how to troubleshoot this further, I want to understand what is leading to this BSOD?
