epoll_wait() failed (4: Interrupted system call)

Hi @alfg , sorry to bother.
I was trying to run nginx-rtmp with docker, and I came across this issue just the same as https://github.com/alfg/docker-nginx-rtmp/issues/29.
```
:~$ docker run -it -p 1935:1935 -p 8080:80 --rm alfg/nginx-rtmp:1.3

I also tried to build it from the source. Although the build was successful, the same issue still occurred.
```

I wonder is this issue solved now? Could you kindly suggest what might be possible solutions for this? Thank you very much.
