Sound like you somehow run out of memory, there is an known issue
with
ZFS which causes livelock when there is memory pressure. Which rsync
version are you using? With rsync 3.x the memory usage would drop
drastically which would help to prevent this from happening.
This isn't known to cause a double fault though. Unfortunately we
probably need more information than was available in order to proceed.
Yes, I agree. But I don't know what to do in this sort of case where
the machine is completely wedged.
