k9s: Occasional hang requiring kill -9

Occasionally, k9s on Linux Fedora 4.20.16-200.fc29.x86_64 hangs. I am unable to input any data into k9s, nor even use Ctrl-C. At this point I have to use kill -9 from another terminal, at which point I can then start k9s again. The terminal itself is not frozen because once the kill -9 is done, the terminal shows k9s as killed, and k9s can be run again in the same terminal.

I don’t know how to reproduce this consistently. If there are some debugging steps I can take the next time this freeze happens, let me know. Perhaps a gdb thread dump?

Versions (please complete the following information):

• OS: Fedora 26, kernel 4.20.16-200.fc29.x86_64, terminal is Konsole
• K9s [e.g. 0.1.0]: 0.5.0 (currently running 0.5.1, will see if it happens again)
• K8s [e.g. 1.11.0]: 1.12.4
