Odd. Maybe it's related to how mpirun starts Cactus; maybe it doesn't inherit the core dump limit setting.  You could try putting it into your bashrc, but that is a long shot.  

You could also try running Cactus directly, i.e. not through simfactory:

exe/cactus_sim ......./static_tov_small.par

However, now that I read your original message again, I see that there is a backtrace printed already!

My guess is that Cactus is being run with a different version of some library than it was compiled with.  It is using /usr/lib/libmpich.  Can you post the optionlist you were using?  Do you have more than one version of MPI installed, or did Cactus build MPI during compilation?
