If you are frequently hit by fsync (as some of the previosly posters told us) 
an option might be to say something as

  tmgr.atom_max_age=30     (or tmgr.atom_max_size=?)

in fstab (or remount the drive in vulnerable situations).

Of course that sacrifices large parts of reiser4's mean performance, but that
might be better than a largely unusable machine. One day reiser4 will be
fully optimized.
