When developing I use COM library. Sometimes (I didn’t manage to identify patterns, I suspect that due to too frequent calls to the COM library) when accessing a COM object or calling a method, the following error occurs:

Ошибка на сервере. (Исключение из HRESULT: 0x80010105 (RPC_E_SERVERFAULT)) 

Unfortunately, I could not give a googling answer why this error occurs and what it means or at least how to avoid it. I would like to know if there is an article that described such errors in more detail ie. at least the cause of their occurrence.

  • Also, if after an error occurs, try to access the COM DLL, the following error occurs: System.Runtime.InteropServices.COMException (0x800706BA): The RPC server is unavailable. (Exception from HRESULT: 0x800706BA) - hngkml
  • Is the library being accessed from the same thread, or different? - Anton Shchyrov
  • From one thread - hngkml
  • one
    Then nothing will help you here. This is the specific work of a particular library. Try to contact the developers - Anton Shchyrov
