Issue

• CPU affinity of a process is set to 15-14 using "taskset" command.
  Eg:

# taskset -c 15-14 ./test.sh > /tmp/test.log 2>&1 &

• Initially it is giving the expected result (i.e task is always using cpus 14-15 )

• But after ~12 hours, the affinity is getting reset and the CPUs reported changed.
