Description M S Vishwanath Bhat 2011-08-11 07:25:30 UTC 
I ran pi the two time in tandem. First time it didn't get any exception. 'Pi' value estimated was correct. But when I ran 'pi' for the second time, I got some exception, but the job itself ran fine. Even here 'pi' value was accurate. 
Gluster volume is of type 'Distributed-Striped-Replicate'. I have pasted the backtrace below.
