It looks like the problem was solved in one of the updates. I cannot reproduce that behavior with the latest PETSc. Thanks!


I'll let you know if it happens again.

1) Is this with the latest PETSc? some of these issues may have been fixed.

2) Please send use something that reproduces the problem and we will fix it. We aren't aware of this problem.
