HI @sta-szek, does it lead to weird behavior or is it just the message you see?

hi @frzifus i just saw your question.
basically it restart the pod in our k8s system - looks like jaeger-operator just die in that case.
its not a big deal, since jaeger-operator is not customer facing service and it is also not jaeger UI itself, so we can just mute alert about pod restart and continue.

anyway, would be good to see why it happens
