My process hangs with the below callstack at WinHttpRecieveResponse(). This behaviour is inconsistent sometime it works for the same data and same use case. But most of the time it hangs likes below.

I have checked using the WireShark that response is received on machine. I can find the response in Wireshark. But the WinHttpRecieveResponse() is not able to receive that data.

Please help me to find the issue.

  • application wait for some data receiving. but no data received. – RbMm Oct 15 '18 at 11:13
  • @RbMm I checked that using wireshark. I can find the response there. the complete data is reached to my machine but not recieved by WinHttpRecieveResponse() api. – Vivek Yadav Oct 15 '18 at 11:24
  • from this thread callstack visible only synchronous `WinHttpRecieveResponse`. are data is received by application, if yes, why event not set - all this invisible – RbMm Oct 15 '18 at 11:27
  • No data is recieved by the application. WinHttpRecieveResponse(Microsoft API) is waiting for the the data – Vivek Yadav Oct 15 '18 at 11:38
  • [mcve] required. – zett42 Oct 15 '18 at 20:59

Found the solution for this problem. Actually before this call there was bufferoverflow which was corrupting my heap. Fixing the bufferoverflow solved my problem.
