unable to run shell script

Dear experts,

I'm using the SSH command to try and run a shell script, it shows that it runs fine but in fact the script doesn't run OR it runs but fails to execute.

The shell script itself runs another python script, that's all it does, it's sort of a wrapper that gives me back an exit code.

The command arguments are:

cd /path_to_script/
./myScript.sh "${arg1}" "${arg2}" "${arg3}"

We're using OO 10.5 and content base 1.6.2, any help would be most appreciated.
