Some processes stay active after killing its PID

[Honza Holakovsky]

Thanks for reply,

I tried to kill the process via all possibilities described in man kill :)
But I didn't know there are some processes which can't be killed, so I tried
again running wdfs, but after "ps -xacu | grep wdfs" I see

USER      PID %CPU %MEM   VSZ   RSS  TT  STAT STARTED      TIME COMMAND
root      971 73,9  0,9 19048  5552  ??  Rs    1:03od   0:15,36 wdfs

no D state :(
I'm quite confused, because in state, I have to reboor every time I umount
wdfs drive :(
