Hi, I am getting the following error in a BBH simulation just before the merger:
> WARNING level 0 in thorn CarpetInterp processor 33 host
> c438-302.stampede.tacc.utexas.edu

Does anyone know why this happens, and if there is a workaround I can use to
get the run going again? Different resolutions of this run, as well as other
runs with similar parameter files, have worked fine. It looks like an edge
case. I am using the trunk ET from 16-Apr-2013.

I have ADMBase::metric_timelevels set to the default, which is 1. Should it be
3? Would it work to recover with this parameter set to 3? The parameter
claims to be steerable, though I don't know what it would use for the
previously nonexistent timelevels.
How about changing the frequency of AHFinderDirect output to match the coarsest
timelevel?
