Kernel errors on running in ARM64

[carlosedp]

I'm running a Prometheus-operator deployment that uses configmap-reload image on a Rock64 ARM64 board.

I see in the logs the following error in journalctl:

In the app logs, I see this error:

2018/03/13 15:14:50 error: function not implemented

2018/03/13 15:15:11 error: function not implemented
2018/03/13 15:15:19 error: function not implemented

It's the only container I see this, any tips on what to investigate? Seems something related to epoll.

After a little more testing, the binary compiled for ARM (export GOARCH=arm) runs without errors but when I compile for ARM64, I get the errors.
