Can you provide a snippet of the pdb file, around the residues listed above?
Or around any earlier residues that give the same "10 oxygen atoms in the
same residue" error? I'm not sure what you mean by the "..." above: showing
the first such message is probably the most helpful. Note that residue
19884 for Amber is probably residue number 9884 in your PDB file, since it
looks like you restart counting after 9999.

Leap ignores chainids.
