[Pw_forum] Memory shortage

[Masoud Rahbar]

Dear QE users
I am calculating the elastic constants of a binary alloy. when the cell
parameter is

6.78 0 0
0 6.78 0
0 0 6.89
there is no problem, but when I change the cell parameter as the following
I run out of memory.

6.85 0 -.03
0 6.85 -.03
-.03 -.03 6.76

Except the mentioned cell parameters everything else is the same in both
inputs. Why is this happening?
