At least you don't have a multi-gigabyte /dev/stdout-file on your system
filled with the output of numerous scripts from years ago :)

I'd guess /proc/self/fd/1 is different for programs invoked from cron,
because cron redirects stdout to catch any output from programs.

Please add something like this:

  ls -al /proc/self/fd/1 /dev/stdout 2>&1 > /tmp/testoutput

to your script and provide the output. Maybe this will be helpful.

Grüße,
Sven.
