 **Problem:** When loading module fabric, created by Ops to solve Issue 2 on NEMO (assertion invalid), EC-Earth enters in a deadlock. Our NEMO benchmark was rather running, but MPI_Finalize was not working and jobs never finished until wallclock time limit was reached.  **Problem:** When loading module fabric, created by Ops to solve Issue 2 on NEMO (assertion invalid), EC-Earth enters in a deadlock.
