Hello,
I was trying to use Epoll pacakge for my nodejs app to detect GPIO2_5 (pin #11 rightmost). But I ran into an error after few seconds of starting the nodejs app:

I posted an issue to the Epoll repository. But the author redirected my to espressobin forum saying it might not be related to Epoll package: https://github.com/fivdi/epoll/issues/25
