Hi Ted,

So i have not been able to recreate this again in my last attempt.
I will try couple of time to see if i can recreate this.

The box under test is a 4 way POWER6. The disk partition (/dev/sda4)
in question is about 19GB.

fsstress was invoked with -p 50 -n 1000 -c -f dwrite=0

Thanks
-Sachin
