Yes, if you can send a test case that would help.
Note that to be thread-safe and reentrancy-safe you
also need to make sure that any managed code you have
that uses Python.Runtime objects or methods is acquiring
the Python lock first. For example:
public class Example {
public static int MethodThatCallsPython() {
// have to acquire the GIL to safely call back into
// Python!!
IntPtr state = PythonEngine.AcquireLock();
PythonEngine.RunSimpleString("print 'hello'");
// done using python for now, so release the GIL...
PythonEngine.ReleaseLock(state);
}
}
Forgetting to manage the lock around a callback into Python
is almost certain to cause a NullReferenceException (because
there will be no valid thread state when the callback is
made).
