Christian,

no, I am not running greyscanner via cron.

However, there is this entry:

# Save some entropy so that /dev/random can re-seed on boot.
*/11   *   *   *   *   operator /usr/libexec/save-entropy

which I have temporarily commented out. The thing is, in terminal, I see this:

I can't figure out what the heck is going on;  what the connection is
between the greyscanner script and the cron errors. Note that the
above is happening every eleven minutes, just like the "save-entropy"
cron entry.

Thanks.

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

See

# man -S 1 crontab

for how to edit or remove a crontab file.
