It seems like a fair error. However, you are working too hard. Make /opt/web/http.py executable, make the first line "#!/usr/bin/python", put /opt/web in $PATH and just say "nohup http.py &" Make sure you are in a directory where you can create and write nohup.out.

If debugging mysteries, nothing beats running it all under strace/truss/tusc with lots of options -faelo /tmp/test/tr -rall -wall -xall or similar, so you can see all the calls and exactly where the error is. Sometimes the report is only half true. Something is missing, but what?

nohup

NOHUP(1)							   User Commands							  NOHUP(1)

NAME

       nohup - run a command immune to hangups, with output to a non-tty

SYNOPSIS

       nohup COMMAND [ARG]...
       nohup OPTION

DESCRIPTION

       Run COMMAND, ignoring hangup signals.

       --help display this help and exit

       --version
	      output version information and exit

       If  standard  input is a terminal, redirect it from /dev/null.  If standard output is a terminal, append output to 'nohup.out' if possible,
       '$HOME/nohup.out' otherwise.  If standard error is a terminal, redirect it to standard output.  To save output to FILE, use 'nohup  COMMAND
       > FILE'.

       NOTE: your shell may have its own version of nohup, which usually supersedes the version described here.  Please refer to your shell's doc-
       umentation for details about the options it supports.
