cvsup mirror updates failing

[stan]

ONe of my cvsup mirros is suddenly getting errors like this:

SetAttrs ports/sysutils/lire/Makefile,v
TreeList failed: Error in "/usr/local/etc/cvsup/sup.client/cvs-all/checkouts.cvs
": 124218: Invalid file type.  Delete it and try again.
CVSup update ends at 2004-03-08 07:41:16

What is this trying to tell me? And how do I fix this?
