"exec failed" means it couldn't start your SQL_feed.pl utility.
Check that it has execute-permissions set. The "Bad address" part 
of the error message is the error reported by the operating
system as result of the exec() function call.

I tried this on the www.xymon.com demo-site using this miniature
shell script:

  #!/bin/sh
  exec /bin/cat >>/var/tmp/rrdfeed.txt

and it seems to work ok. Here's some sample data:
