You could use the standard client "procs" test (or a custom
version based on it) to check for your problem script and then
use an initial page delay to prevent it from triggering an alert
unless it over-runs. With this approach, the BB display will
turn red while the script runs, so it may not be ideal for your
environment.

The alternative would be to create a temporary "flag" file as
the first operation of your script and delete it at the end.
You could then use a custom extension script (or one of the
file monitor examples from the "deadcat" site) to trigger
an alert if the file exists and is older than a specified
amount.

Cheers, Phil.
