CursorNotFound - Githubissues

Подскажите пожалуйста с чем эта может быть связана, и как её лечить/избегать:

Если дать больше вычислительных ресурсов, то отрабатывает нормально:

Первая ссылка по поводу говорит, что сюда https://github.com/WLM1ke/poptimizer/blob/084ac14ca6212a5b14bea5bbc9bb575da077ffb0/poptimizer/evolve/population.py#L239 можно добавить параметр no_cursor_timeout=True

в ту сторону смотрю? там правда есть уточнение not valid at server, а здесь такого нет...
