Todaj another software on a machin running the same environment got native
stack trace:

** (MpkCollector.exe:2950): WARNING **: Shutting down finalizer thread timed
ERROR:error.c:70:SetLastError: assertion failed: (ret == 0)

  at MpkCollector.RequestThread (object) <0xffffffff>
  at MpkCollector.RequestThread (object) <0x003aa>
  at (wrapper runtime-invoke) object.runtime_invoke_void__this___object
(object,intptr,intptr,intptr) <0xffffffff>

Native stacktrace:

Debug info from gdb:

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
