A random, but interesting datapoint: the fts_read() failure seems to be correlated to the processing speed (CPU and RAM) versus the speed of the disks. On one of the RE build machines, prior to r268376 in head/, I could consistently reproduce this particular build failure when building with '-j' values of 24+. On one of the newer RE machines, both world and kernel are build with '-j48', and I have yet to see this particular build failure in the stable/10 branch. The main difference between the two machines is that the second machine mentioned is configured with proper partition alignment and ashift=3D12 versus ashift=3D9.
