ok So I had a look, I have the following stacks for each top thread:

ntdll.dll!wcsicmp+0xe
RPCRT4.dll!RpcBindingSetOption+0x836c
RPCRT4.dll!RpcBindingSetOption+0x7d1e
RPCRT4.dll!RpcBindingSetOption+0x301b
RPCRT4.dll!I_RpcNegotiateTransferSyntax+0xd4
RPCRT4.dll!Ndr64AsyncClientCall+0x40e
RPCRT4.dll!Ndr64AsyncClientCall+0x13d
iaStorAfsServiceApi.dll!OptaneRegisterListener+0x1392
iaStorAfsServiceApi.dll!OptaneRegisterListener+0xf9e
iaStorAfsServiceApi.dll!OptaneRegisterListener+0x5ad8
KERNEL32.DLL!BaseThreadInitThunk+0x14
ntdll.dll!RtlUserThreadStart+0x21

and

RPCRT4.dll!RpcBindingSetOption+0x8362
RPCRT4.dll!RpcBindingSetOption+0x7d1e
RPCRT4.dll!RpcServerUnregisterIf+0x677
RPCRT4.dll!RpcServerUnregisterIf+0x62a
RPCRT4.dll!NdrFullPointerQueryRefId+0xe44
RPCRT4.dll!CreateProxyFromTypeInfo+0x17e
RPCRT4.dll!NdrClientInitialize+0x2e50
ntdll.dll!LdrAddLoadAsDataTable+0x339
ntdll.dll!RtlReleaseSRWLockExclusive+0x694
KERNEL32.DLL!BaseThreadInitThunk+0x14
ntdll.dll!RtlUserThreadStart+0x21

I'm not quite sure what to make of it, but I'm assuming DOPUS is not the culprit in this instance?
