:sure,
It's worth turning off nqnfs and sticking with normal nfs to see
if the crashes go away. If they do go away then we know where
to look and might have a better chance tracking down the problem.
So far I haven't been able to make heads or tails of your crashes...
it's like something is randomly corrupting memory. My best hope
was that the UPAGES fix would solve the problem but it seems that
it hasn't.
