Fuel CLI throws error

[Sergii Golovatiuk]

This bug was found on 5.0.1 environment. When you run

fuel node

it generates this error

[root@fuel ~]# fuel node | grep control

This issue is sporadic. "fule node" may work on one run then may throw error, then work again.

[Vladimir Sharshov (vsharshov)]

Rare error. Workaround: run command again. Known issue. Moving to 8.0

[Maciej Kwiek (maciej-iai)]

I was not able to reproduce it, I ran this command:

time while fuel node; do :; done

to run fuel node for 83 minutes, there was no error. Marking as incomplete, need steps to reproduce.

[Vitaly Sedelnik (vsedelnik)]

Won't Fix for -updates milestones because of Medium importance

[Maciej Kwiek (maciej-iai)]

Could not reproduce, marking as invalid.
