Buildbot failure in MUMPS factorization phase

[Martin Sandve Alnæs]

This error occurs regularly. Would be nice to fix.

@garth-wells This buildbot also has petsc 3.4.2. Do you think upgrading will fix?

Software versions: http://fenicsproject.org:8010/buildslaves/trusty-amd64-py3

However this one is stable green and also has 3.4.2: http://fenicsproject.org:8010/buildslaves/trusty-amd64

An update might very well help.

The Debian/Ubuntu packages really shouldn't be used; they're unsupported and full of bugs. PETSc really needs to download its own dependencies because it picks compatible versions and applies patches for bugs that upstream packages don't seem to care about fixing.

Removing milestone: 1.7 (automated comment)

Hasn't been observed for some time. Probably fixed by updates.
