Hi,

Last night, I found my system was very heavy while I was
getting crc of all files in 80GB file system to check the
status of backup.  When I checked the system, "find" program
looked like the reason of the problem.

  $ ps aux
  USER    PID %CPU %MEM  VSZ   RSS TT STAT STARTED    TIME COMMAND
  root    6776 11.5  0.2 404852   600 p4 S+    6:16PM  3:16.66 find . -type f -ex

First, I doubted find program itself, but it didn't allocate
any additional memory after the initialization.  So, I guess
fts uses memory.  Is there any option to reduce this?  Using
404MB is too bad.  Thanks.


In addition, this is the output of vmstat while my machine
was heavy.  It seems that the number of page out is too
much.

  $ vmstat 5
   procs   memory     page                       disks         faults      cpu
   r b w   avm   fre  flt  re  pi   po   fr   sr w0 w1 w2 w3   in   sy  cs us sy id
