No such process.
Many proccesses waiting at vmpfw are 'cron'. It may be because I run 
package build on MFS during night and found the machine freeze when I
woke up.

All states that can be found is:

accept
getblk
inode
nanslp
nfsd
nfsidl
pause
ppwait
psleep
sbwait
sched
select
ttyin
vmpfw
wait
wmesg
wswbuf
