Dashboard enters crash loop

[neuromantik33]

Hello,

I'm running an onyx cluster in Kubernetes and also run as a Deployment an onyx-dashboard using the official docker image. Occasionally, when performing deployments my dashboard enters a crash loop as seen below and I'm forced to delete the pod, and things correct themselves, until of course the next occurrence which is several times per day.

I'm unable to understand why this is the case, my cluster is running, and there are always peers even if no job is currently scheduled or running. Any help on the subject would be much appreciated.

@neuromantik33 Which docker image are you using?

onyxplatform/onyx-dashboard:latest (outdated) or onyx/onyx-dashboard:latest

The problem has disappeared once migrating to the latest 0.13.0.1 version however I have additional problems but I will file a new issue.
