   There seem to be several reports of reiserfs falling over when memory is
   low.  It seems to be undetermined if this problem is actually reiserfs or MM
   related, but there are other threads on this list regarding similar issues.
   This would explain why the same disk would work on a different machine with
   more memory.  Any chance you could add memory to the box temporarily just to
   see if it helps, this may help prove if this is the problem or not.


If you caught the end of the thread, james (the initial poster) added
memory, had no problems, removed the extra memory and still had no
problems.  His spare memory is greater than my memory total.  I too
cannot repeat the freeze.  It makes me wonder if there is some
parameter updating in the kernel somehow.
