portsnap fails: look: tINDEX.new: File too large

[Hartmann, O.]

Since today's morning I receive on every box this message shown below
while doing a 'portsnap fetch'.

What's wrong and how to repair?

Regards,

Oliver

Looking up portsnap.FreeBSD.org mirrors... 5 mirrors found.
Fetching snapshot tag from portsnap1.FreeBSD.org... done.
Fetching snapshot metadata... done.
look: tINDEX.new: File too large

Portsnap metadata appears bogus.
Cowardly refusing to proceed any further.
