This happend on a rather higher load situation, when I was copying a 200G file from a snapshot back to it's original place on its zvol, when this happened. Luckily these are RSF-1 nodes and the other one took over very quickliy, such as that my VM cluster didn't even seem to notice this issue. However, at that time I was conencted to the crashing host via ssh and my heart skipped a beat. ;)
As I have (unvoluntarily) freed this node of it's duties, I could jump to r020 on it, but I wonder if there has been any changes to the scsi_vhci layer at all in recent times…
