Hi Erik.
OK, I reran again, with veryverbose and CarpetLib::output_bboxes=yes. Much larger output -- about 3GB in toto, Tarred + Zipped to about 271MB, is now on WebDrive:

Again, the username/password = beanykelly/helpmercurial.
Thanks,
Bernard

Thanks for the data.
My preliminary analysis shows that there is a small box, 1 grid point wide in the y direction, located near the centre of the domain and somewhat near the lower z (symmetry) boundary, where Carpet cannot find a source to synchronise ghost or buffer zones. The problem is not at the symmetry boundary, and the region does not seem to have a regular extent.
It seems that the ghost zones on level 10 are to be filled by buffer zones on level 9, which is not allowed. This would be an error in CarpetRegrid2, which needs to ensure proper nesting, or an error in Carpet if it determines the location of buffer zones incorrectly.
Can you re-run with CarpetRegrid2::veryverbose=yes?
The output of CarpetLib::output_bboxes=yes would also be helpful, but may be too large, unless you manage to restart from a checkpoint just before this problem occurs.
