I tested your GAMESS output file & it looks OK for me. However, there
is something that looks strange to me at the beginning of your QM

cp OXL.inp .//OXL.F05
unset echo
setenv ERICFMT .//ericfmt.dat
setenv MCPPATH .//mcpdata

My understanding is that OXL.F05 should be in your scratch directory.
So if you copy OXL.inp into .//OXL.F05. Does it mean that your
'working' directory is your 'scratch' directory ?

Here is what I get when I run GAMESS on my machine:
[fyd.localhost ~/GAMESS]$ rungms test > test.log
cp test.inp /usr/local/0QM_SCR/test.F05
unset echo
setenv ERICFMT /usr/local/gamess/ericfmt.dat
setenv EXTBAS /dev/null
setenv IRCDATA /usr/local/0QM_SCR/test.irc

I run GAMESS from the "/home/fyd/GAMESS" working directory & my
scratch directory is at "/usr/local/0QM_SCR/"

Or does it mean that in the last GAMESS version the "rungms" script
has changed ?
I tried to get the last version of GAMESS without success since the
GAMESS MySQL/PHP download system seems broken. Did you modify the
"rungms" script, can you send me your "rungms" script ?

BTW, you might consider using PC-GAMESS (if your machine is a PC)
since it looks really faster than GAMESS-US.

Your P2N file is not correct. Please, see the one I sent you. Your 1st
column of atom name is not correct: The four oxygen atoms should be
chemically equivalent. The two carbons should also be equivalent.

Please read also the tutorial .
Read in particular the sections:
- General information about charge fitting
- Rules followed by the R.E.D. program for automatic RESP input generation
- Limitations of the R.E.D. versions I and II and creation of the P2N
file format
And, see an example of P2N file .
