Comment (by wolfgang.kastaun@…):

 Additional remark: setting the parameter Carpet::prolongation_order_time =
 2 fixed our problem, but it had to be changed from the beginning, not just
 in the restart. Otherwise, the restart crashes with

 terminate called after throwing an instance of 'std::out_of_range'
   what():  vector::_M_range_check
 Rank 2 with PID 7145 got signal6
 terminate called after throwing an instance of 'std::out_of_rangeterminate
 called after throwing an instance of ''
 std::out_of_range'

 from the backtrace, it crashes in
 CarpetIOHDF5_RecoverGridStructure+0x1332
