>
> On a CloudStack 4.10 setup running with Basic Networking we noticed VMs being in the "Starting" state.
> After investigating in the VR we show the "ip rule show" command run for ever and never end. This causes Python scripts to wait and thus never start the Instance.
> This seems to be a issue in CsHelper.py where it uses p.wait() which might block in certain situations.
