I too did 24 hours of non-stop runs on 16 processors (about half on 16
dedicated nodes of 1 proc each, and half on 8 nodes using both procs)
on:

    x86:  gm-1.5.1 mpich-1.2.4..8a
    ia64: gm-1.6.3 mpich-1.2.4..8a

Compiled with gcc -g.  Both never caused errors using input.final.0.

Didn't the CPlant/NM guys have a similar issue with corruption on alpha
that ended up being a glibc issue?  I could be misremembering, but you
might ask Ron.
