If you get an error from *cron* it means that greyscanner is executed
from cron itself. As root, you might want to an

# crontab -l u operator

to find out if this is true. The format of the crontab-file is explained in

# man -S 5 crontab


# man -S 1 crontab

for how to edit or remove a crontab file.
