Problem summary

• With JR42993 patch installed and env. var
  DS_GENERATE_UNIQUE_JOBID=1 a parallel job which fails at an
  early stage may 'hang'.
  The job log will include a FATAL log event but the job's DSD.RUN
  and DSD.OshMonitor processes continue running and the job
  remains in the Running state.
  
  The underlying bug in DSD.OshMonitor is that it gets a component
  error before the component has started and the num_running count
  is decremented below 0, and the exit test is for num_running =
  0.
  
  The issue is related to JR42993 only because when we use pid as
  job id we can test whether the process is still alive.
  

Problem conclusion

• Fixed DSD_OshMonitor to handle component error and terminate in
  a timely fashion.
  

Temporary fix
