[Pw_forum] problems with programme stopping

[Mousumi Upadhyay]

Dear All,

            In PWSCF, am running some structural relaxation jobs.
there, most of the times, the jobs are stopping with an error 
msg,

                                                                                          
     entering subroutine stress ...
                                                                                
          total   stress  (a.u.)                         (kbar)     P=

     Eold  =   -798.02648163
     Etot  =   -798.02650981
     DEold =     -0.00005398
     DEtot =     -0.00322997
