Nohup not working as expected

Hi. I am trying to start a script on my router that will execute even if i log off. To execute the script I write:

nohup ./dslconnection > dslstat.out 2>&1 &

It starts the job:
21968 admin 1604 S /bin/ash ./dslconnection

The problem is that when I log back in the job has been terminated.

To debug I tried the same thing with ping.
nohup ping 192.168.1.91 > dslstat.out 2>&1 &

This worked and ping was still executed when I logged back in.

The script I want to run is below. Any ideas of what could be the problem??

Code:
#!/bin/ash
statusname=0
while true
 do
        laststatus=$statusname
        ping -c 1 -W 1 www.google.se > /dev/null
        statusname=$?
        if [ "$statusname" -ne "$laststatus" ]; then
           date
           if [ "$statusname" -eq 0 ]; then
                  echo Google is reachable
           else
                  echo Google unreachable
           fi
        fi
    sleep 10
done

STARTFLUXBOX(1) 						  Fluxbox Manual						   STARTFLUXBOX(1)

NAME
startfluxbox - start a fluxbox session SYNOPSIS
startfluxbox DESCRIPTION
startfluxbox is a script which runs the file ~/.fluxbox/startup If it doesn't exist it will be generated. startfluxbox should be started from your ~/.xinitrc if you use startx, or ~/.xsession if you run a display manager, like xdm. FILES
~/.fluxbox/startup This file contains all commands that should be executed before fluxbox is started. The initial file contains helpful comments for beginners. It also starts fluxbox. EXAMPLES
The default ~/.fluxbox/startup is as follows: #!/bin/sh # # fluxbox startup-script: # # Lines starting with a '#' are ignored. # Change your keymap: xmodmap "$HOME/.Xmodmap" # Applications you want to run with fluxbox. # MAKE SURE THAT APPS THAT KEEP RUNNING HAVE AN ''&'' AT THE END. # # unclutter -idle 2 & # wmnd & # wmsmixer -w & # idesk & # And last but not least we start fluxbox. # Because it is the last app you have to run it with ''exec'' before it. exec fluxbox # or if you want to keep a log: # exec fluxbox -log "$fluxdir/log" If you need to start applications after fluxbox, you can change the exec fluxbox line above to something like this: exec fluxbox & fbpid=$! sleep 1 { xsetroot -cursor_name left_ptr -fg white -bg black & ipager & gkrellm2 & } & wait $fbpid So xsetroot, ipager, and gkrellm2 will all be started after fluxbox, after giving fluxbox 1 second to startup. For more details on what else you can do in this script, see sh(1), or the documentation for your shell. AUTHORS
