On 7/6/2015 I was standing on the sim Moors of Elmandria camming around at different things I got an Nvidia error 8 before the viewer closed. I went ahead and logged back in for my viewer to close again with the same error in less than 5 minutes. My system has bridged GTX 970s that are amble to handle a lot more than what SL should be able to throw at them. I wasn't aware of this is a known issue, or if there is a way to resolve this or not.
