I attach parfile and thornlist toreproduce. This uses rev 4997 of the flesh.

    I can't seem to reproduce this one. Can you check this is still a problem in the latest development versions of codes? What machine did you run on?

    I note that in my efforts to build it and run it I need other thorns (SymBase and CoordBase). I also got an error message from carpet about needing to parameters differently, e.g.. set initial_data_setup_method="init_all_levels"

    Still happens with a fresh checkout on QueenBee. The Cactus tree is at /home/rhaas/Cactus_Piraha and I did a:

    exe/cactus_sim -S par/test.par

    The thornlist used to download the code (on QB) is in thornlists/ThornList. Svn info returns the flesh version as 4997.

    Note that since it fails so early for me, I never included the missing thorns (I assume their presence is only checked afterwards). The folder should be world readable.
