You could also look at using existing s/w for monitoring processes like monit. I don't know your exact usecase but you could make your process as a 'service' and have something like systemd or upstart monitor it. These tools will typically 'restart' the hung process on detection. -mandeep On Fri, Nov 29, 2013 at 5:58 AM, Vipul Jain <vipulsj@xxxxxxxxx> wrote: > Hi Kernel alias, > > I am a newbie and I am trying to figure out ways where in I can recover the > Linux in below two scenarios: > 1. my specific process hangs. > 2. kernel gets hung partially or completely. > > I have done some reading and seems like there is softlockup and hardlockup > mechanisms in Linux source base that I can use but not sure, if yes I have > below questions: > 1.
