This is a very interesting issue.
1. Are you sure that your user account has permission to create result directory, /home/snataraj/test/threads/bfs/bw128 ?
2. It seemed that collection duration is long, do you have any problem to run collection shortly? Specify "-duration 60" for example.
3. Do you have any problem to collect with other simple application? For example, "amplxe-cl -collect advanced-hotspots -r /home/snataraj/test/threads/bfs/bw128 -- /bin/ls"

If collector was not exited abnormally (killed by user, ctrl-C is allowed), Verify if tb6 file is corrupted, use Finalizing:
amplxe-cl -finalize -r /home/snataraj/test/threads/bfs/bw128

Did you mean above error message was generated by program itself? If program worked without VTune, it ran smoothly?
It seemed that was due to data send/receive time-out, my opinion is to use PMU event-based sampling instead of user-mode sampling to reduce overhead, and note not to enable call stack collection which might add overheads. Another way is to enlarge SAV value, to reduce sample counts.
Hope it helps.

@Surya
Are you collecting data over network?

I log into the network...i,e the xeon host...then I use the vtune which is in host and launch my collect from the host...where the script runs the natie application in phi.
amplxe-cl -collect-with runsa-knc -knob event-config=CPU_CLK_UNHALTED:sa=100000,HWP_L2MISS:sa=100000 -- ssh mic0 "script.sh"

I would like to advise you to use wireshark to monitor connection between host and Phi coprocessor(if I understood your description correctly).
