Additional context

Here's the resources definition of che-operator's deployment :

        resources:
          limits:
            cpu: 500m
            memory: 256Mi
          requests:
            cpu: 100m
            memory: 64Mi

Actually I can get around the issue by modifying these limits values.

@coutantal
Could you provide working limits?

@tolusha what do you mean by working limits ?

I have no namespace or cluster-wide limitation for pod's resources.
