LAPACK/ScaLAPACK Development

I have a problem. Code runs ok up until 2000 data rows. Once I have increased it to more than 200 rows it gives me a error and stops.
Error message:
** On entry to DPOTRF parameter number 4 had an illegal value

Can you please help me in solving this problem.
Thanks.

This error message means that your fourth argument (LDA) is smaller
than your second argument (N). This is not correct. LDA needs to be greater
or equal than N in any case.
