c++ WSARecv Server crashes on Windows

  alloc, c++, heap-dump, iocp, windows

our server have Intermittent network module problems
Dump point : WSARecv

Any help would be greatly appreciated.

Maybe using some compiler directive can help?

We build the executable in VS2017 in Release/x64

Dump Call Stack :

    ntdll.dll!RtlpLowFragHeapAllocFromContext()  
    ntdll.dll!RtlpAllocateHeapInternal()    
    ws2_32.dll!WPUModifyIFSHandle()  
    ws2_32.dll!DCATALOG::FindIFSProviderForSocket(unsigned __int64)  
    ws2_32.dll!DSOCKET::FindIFSSocket(unsigned __int64) 
    ws2_32.dll!WSARecv()

VS says that (simple)command line is:

/Yu"PCH_server.h" /MP /GS /GL /W4 /wd"4100" /wd"4702" /wd"4996" /wd"4091" /wd"4366" /wd"4324" /Gy /Zc:wchar_t  /Gm- /O2 /sdl
/Zc:inline /fp:precise /D "NDEBUG" /D "_CONSOLE"  /D "_WIN64" /D "_RELEASE" /D "_UNICODE" /D "UNICODE" /errorReport:prompt 
/WX /Zc:forScope /Gd /Oi /MT /FC   /EHsc /nologo  /diagnostics:classic

Additionally, our server is Multi Thread

I don’t know why crash WSARecv

not a make SocketError, just crash
