one of my BNS simulations with the Spritz code started from a checkpoint and, after running for about one day, crashed with exit code 8. The error seems to be related to the Einstein Toolkit infrastructure, so I am posting this message on this mailing list. I am attaching the stdout and stderr (even though they don't look very informative) and the backtrace.

Running addr2line -e <Cactus executable> <address> with the <address> listed at point 3 in the backtrace, I see that the error originates from Cactus/arrangements/Carpet/CarpetLib/src/defs.hh:144 . In order to see how we get to that point, I am listing here the files and line numbers corresponding to points 4 to 11 in the backtrace (points 12 and 13 are not relevant I think):

8.   Cactus/arrangements/Carpet/Carpet/src/OutputGH.cc:51

10. Cactus/arrangements/Carpet/Carpet/src/Evolve.cc:703

11. Cactus/src/main/flesh.cc:88

Visually, the 1D and 2D output does not show any obviously wrong features, so I have no clue about what is going on. Do you have any ideas?

I am also attaching the parameter file I am running with and the optionlist I used to compile. Kindly let me know if I can provide further info and/or attach any other file you may find useful.

Thank you very much in advance for your help,
