[petsc-users] Error: Invalid MIT-MAGIC-COOKIE-1

[Satish Balay]

Perhaps it coming from HWLOC [due to bad X11 setup on this box]

Something to try:

PETSc, by default, should not be doing anything with X-Windows calls unless a specific option related to X windows is used even if PETSc is compiled and linked against X windows. These test runs are not using anything related to X-Windows. Just having the X windows libraries linked into the executables should not produce such messages so why are they appearing?
