Comment (by anonymous):

 1. This is Nov 15 2015 release
 2. I'm using the tool included BBHMedRes.par
 3. In directory: Cactus/exe: sim/mpirun -np 10 ./cactus_sim BBHMedRes.par.
    I have a Xeon 2620 with 6 cores. I have also observed this with np=2,
 np=5.
 4. It runs between 1min and 4 hours and suddenly it just freezes, see
 attached screenshot
    of frozen system. Keyboard/mouse are not communicating, the screen is
 no longer
    updating, network connection is off etc. Also the sim also stopped, I
 have waited an
    hour or so to see if during this time the simulation files were
 updating. But no.

 I don't think it's a memory issue since I'm quite a bit away from my max
 24GB/64GB.
