Mô tả
I am running a cluster with Linux/windows machines.
I cannot any longer use scatter/gather/pull/push variables.
In windows this is the error the engines print in the screen

On linux it generates a seg fault.
On the session I am using as a console (linux) I get the following
`In [6]: dview["qwerty"]=33
In [7]: dview["qwerty"]

I am on python 3.5.2, using ipython 4.0.2 and ipyparallel ( all systems ) 6.0.2
I checked google and this does not look like being reported by anybody else.
This has worked fine in the past. First time I am facing this issue
