Hello Walter, 

thanks for the  reply. 

The error message starts like this and continues.

the 1 cpu job has the same error.

It has been a while since I ran it, and the implementation of Mohr
Coulomb has changed a lot since then.  I should run it again.

It may be that petsc is catching a place where Gale is writing to
invalid memory.  What is the exact error that you get?  For the small
model, can you run it on one processor?

I am out of town right now, so it will take me a few days to run these
models again.
