Running decomposePar when the controlDict has probe locations in it gives rise to warnings as shown below:

---------------------------------

After running the case and reconstructing the stored times, when we run paraFoam, it crashes instantly.

Solver/Application:
icoFoam (but it could be just about any solver)

Source file:
libsampling.so?

Testcase:
Try the cavity tutorial in parallel. No special settings. Just remember to add some probelocations in controlDict.

Platform:
linux64

Version:
(OpenFOAM 1.4)

The best way to avoid these warning messages is to remove the probes from controlDict while performing the decomposition. If you would rather not do this but would still like to avoid the warning message then remove lines 60-70 from OpenFOAM-1.4/src/OpenFOAM/db/dlLibraryTable/dlLibraryTableTemplates.C
and recompile.
