[ovs-dev] Open vSwitch crashes when running NOX with some components

[Derek Cormier]

Hello,

I wasn't really sure if this belongs on the OVS or NOX message board, 
but here is the problem. I am trying to use the NOX GUI, so I run NOX with:

nox_core -i ptcp:6633 pyswitch monitoring discovery lavi messenger 
jsonmessenger

However, when I run nox_core with components other than pyswitch, Open 
vSwitch crashes with a segmentation fault immediately after it connects. 
As for why I am using those exact components, I don't really know. I 
remember reading somewhere that I should use these for the GUI.

The same thing happens with NOX 0.9.0 and 0.9.1. I am using Open vSwitch 
1.1.0pre2.

Here is some OVS output:
