Exiting from top causes container to shut down #47

Open lePereT opened 4 years ago

For the previous issue I used top inside the container to determine that something was up with urngd. However, consistently when leaving top with a ctrl + c it causes the container itself to crash.

To replicate: 1) docker run --rm -it openwrtorg/rootfs 2) top 3) ctrl + c 4) wait 2 seconds

On some further digging, I think it's related to the errror message that appears just above the banner on login using the Readme command of docker run --rm -it openwrtorg/rootfs, which is /bin/ash: can't access tty; job control turned off

This looks like it means that advanced tty functionality like ctrl + c is unavailable

So this gets weirder, and it's now exceeded my capacity to diagnose. Using the readme's command docker run --rm -it openwrtorg/rootfs leads to the issue here and the previous one I posted in #46.

However, if I use docker run -it openwrtorg/rootfs it again displays the same problems. But if I restart the crashed container then it behaves seemingly perfectly (except that urngd starts using 100% of CPU after a few hours good behaviour) . Any idea as to what's happening here?

I'm aware of the ctrl + c (SIGINT) issue, however don't know how to fix it. If you come up with an idea please help me out.

@lynxis do you have an idea regarding the tty access trouble?
