Hi,

Could it be that you use more memory than available on the computer ?

I am using abinit 5.5.4, and openmpi 1.2.8.  I am running on 10 processors on 2
computers, using Terminal on Mac OS X 10.5.

One thing I'm seeing over time as I calculate response functions is that the
processor usage is going down, although not steadily.

My previous run was over 450 hours before the MacOS X crashed.  It's usage
(according to Activity monitor) was at 65% last I checked, on average, for each
of the 10 abinip processes.

I started a much shorter run recently, and I expected it to be done already.
Instead it's at 22 hours, and still "running", at 85% across the board.  It
dropped to 85% sometime in the first 10 hours, has been steady ever since.

Is this expected?  Or is it a sign of a bug/error/hang?
