NFS-server at the other end. Seems autofs/nfs releated.

Already fixed in 2.6.28 by the following commit.
  http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git&a=commitdiff&h=9a4bd29fe8f6d3f015fe1c8e5450eb62cfebfcc9

You should probably also apply the following commit (also in 2.6.28),
which fixes a memory leak in the same area.
