Hi Friends,

I have one programme which is in Fortran. it is for postprocessing of Jet, it is having bunch of commnon blocks(arrays) which r very huge in size. I am reading the data in to seven arrays each of its size is approximately 66*98*616 first my programme was running, second time i tryed run the same programme without changing any thing, it is giving segmentation fault and fort.30 file. i reduced the array sizes, again this programme is running. I am very confussing why it is behaving like this, first time ,why this programme was running for big size arrays, why not in second time.. please help me..
