I have a code based on openfoam-2.3.x (Could be ported to newer version but,.... the usual excuses).

When I put it through valgrind I get the following messeages. Any thoughts and comments. Code seems to run fine normally.

I run a centos7 48 core shared mem system, 12 mpi ranks, gnu compilers and openmpi-1.8.8.

Thanks in advance for your help.
