Occasional reconciler error

[kuritka]

k8gb_gslb_error_total metric revealed , an unexpected error generated inside the controller runtime. From my observation, the error is not critical to the functioning of k8gb, it just messes up the metrics. Find out what in k8gb is causing this error and make the necessary changes.

the error occurs very little and appears after a while of running on localhosts

@kuritka is this still the issue?

Hi @somaritane, just checked locally. Yes, the Reconciler error still ocurs.

@kuritka it very frequent situation for k8s based projects. Please see how it was handled by crossplane runtime https://github.com/crossplane/crossplane-runtime/pull/498 . TL;DR : let's just move such events to debug log level of minimal importance
