[petsc-users] parallel IO messages

[Dave May]

There is little information in this stack trace.
You would get more information if you use a debug build of petsc.
e.g. configure with --with-debugging=yes
It is recommended to always debug problems using a debug build of petsc and
a debug build of your application.

Thanks,
  Dave
