      with?&nbsp; I 'assume' you are using 13.1.&nbsp; Hopefully, you are not
      using 12.1, because mBJ sometimes did not work in that older

      What Intel Fortran compiler version are you using?&nbsp; I suspect that
      the problem is caused by the compiler making a bad lapw0
      executable.&nbsp; That might happen if the compiler has a bug or bad
      compiler settings are used [

      <a class="moz-txt-link-freetext" href="http://en.wikipedia.org/wiki/Segmentation_fault">http://en.wikipedia.org/wiki/Segmentation_fault</a> ] might also
      happen because of other things like not having enough random

      Is your Linux 32 or 64 bit?&nbsp; Traditionally, 32 bit Linux cannot
      recognize more than 4 GB of RAM, even though you might have more
      physical memory than that in your computer case.&nbsp; Though, some
      modern Linux distributions can get around that [

      <br>
      I think it is not likely a problem with your calculation setup and
      steps, or your other mBJ calculations run fine except this one?<br>
