Hi
I hit this bug, on a 2x2 replicated:distributes volume: It does not reproduce
100% off the time, but works (well, breaks) most of the time:
# echo "xxx"|cat -l > test9

This line is the point to debug deeper. Can you put a breakpoint here in server_lk_cbk and print the backtrace why errno is ENOENT? The rest of all the observations are cascaded effects.
