I don't think this will fix your issue since this is a internal extraction.
Try using: -Ddrill.exec.enable-epoll=false in your drill-env. That should
(hopefully) disable the extraction of epoll drivers (which should actually
be disabled by default I believe due to disconnection problems in heavy
load cases).
