This is the sort of errors you may need to dig into a bit more at your end.
We should first try to find out if this caused by hardware issues. I suppose If you can experiment by swapping RAM back. RAM issues should also cause crashes that are not OVS related. If you can rule out RAM change being the cause, I'd suggest try version OVS 1.4.6 -- There are a few datpath bug fixes on the 1.4 branch that may be related.
