I have modified the parameter discard the old builds to 7 number since the Jenkins fill entire disk  with log . 
 
But still the job is looping..
 https://jenkins.iotivity.org/view/iotivity-merge/job/iotivity-merge-master-windows-x86-vs2013/-
 
I am unable to sort this odd behaviour  and also observed is it ran 16 hr/20hr , yesterday more that 3 hr so i manually stop the job.in this case i can go with build time out option as 1 hr. i.e if the build trying to run more than1 hr in the next sec Jenkins will kill the job.
 
 
the job is looping at this below log
