After a few (10-15) test re-runs and/or restarts the application fails with "too many open files".

The error is when the Fabric8 K8s client is attempting to initialize; it seems like it might be leaking K8s clients upon restart.

Do you have a stack trace? What exactly causes the issue? Running in dev mode? Something else?

Yes. This was while running dev mode only and making changes with it restarting while making changes.

@kdubb sorry for the long reply delay. I wasn't able to reproduce the issue. Is it still something that is a problem for you?
