I upgraded to 2.0.1.11 yesterday.

Since then I have noticed that excavator is mining ok, then all of a sudden I see red lines and it restarts.
Its mining equihash with 8 x nvidia GTX 1060 3gb
It hasn't been doing this with earlier versions, it would go for days.
Once I saw this tonight I went to the log files to see what the errors are, the lines below keep coming up and it looks like its just before it restarts.
The errors below are in the log files at where it looks like it restarts.
