pkg fetch -a

[Coert]

Hello all,

In relation to my question about /var/cache/pkg and Matthew's answer,

I am now doing pkg fetch -y -a -o /data/mirror/pkg/
It runs for a while, and now repeatedly bombs out with:

pkg: cartotheque-0.1_6 failed checksum from repository

If I restart it, it continues where it left off, successfully 
downloading the package.
Am I doing something wrong? I tried pkg update -f a few times but no 
difference.

And our internet connection at my place of work is good and reliable.

Any ideas?

Kind regards,
Coert
