Hey @nemanjac . Thanks for reporting this. Are you still getting this issue with the latest version (v1.1.5) by chance?

Sorry @michael I was away for short vacation here.
I just checked again

2021/05/04 15:34:18 [emerg] 63#63: io_setup() failed (38: Function not implemented)

This line still comes in error reports.
I’m not experiencing blockages any more, which is good. But error remains.

Thanks @nemanjac,

Our developers are looking into this but haven’t been able to reproduce it just yet. We’ll keep trying and we’ll update you here once we know more.

Hi @jeff
Sounds good.

It is running fine now. It seems that the error is not causing any issues anymore.
It might have been something I did, as I was testing series of scripts that can customize docker fpm and nginx automatically.

Cheers,
Nemanja
