Maybe something like this, if I understand correctly:

Code:
while sleep 10; do
  grep STARTUP nohup.out > temp.x
  lines=`wc -l temp.x`
  if [ $lines -gt 1 ]; then
    echo STARTUP occured twice in nohup.out
    # Do whatever needs doing
  fi
done

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.
