First, you need to manually examine the mol2 and frcmod files that were
created. We don't have any idea how you created these files, but they
can you help a lot in debugging.

So, is there supposed to be a bond between C10 and C11? Is the distance
in the mol2 file really 4.9 Ang? This suggests that the pdb file you used as
input to antechamber was badly flawed (check that). If the input geometry
is not reasonable, antechamber will fail.

This sounds odd: is the charge supposed to be 15?

Look in the mol2 or lib file: is there a type for O22?
Based on very limited evidence, it looks like antechamber did not do what you
expected it to do.
