ports database updating failed

[corl3ss]

Hello all !

Since yesterday (before it was running very well for a while), when I 
run this very small script :
--
cd /usr/ports &&
csup -g -L 2 /root/cvs-supfile &&
portsdb -uU &&
--
Where my cvs-supfile is:
---
src-all
ports-all
doc-all
www
cvsroot-all
---
The csup is ok  but the port database updating failed (see below)...
---

********************************************************************
Before reporting this error, verify that you are running a supported
version of FreeBSD (see http://www.FreeBSD.org/ports/) and that you
have a complete and up-to-date ports collection.  (INDEX builds are
not supported with partial or out-of-date ports collections -- in
particular, if you are using cvsup, you must cvsup the "ports-all"
collection, and have no "refuse" files.)  If that is the case, then
report the failure to ports at FreeBSD.org together with relevant
details of your ports configuration (including FreeBSD version,
your architecture, your environment, and your /etc/make.conf
settings, especially compiler flags and WITH/WITHOUT settings).

Note: the latest pre-generated version of INDEX may be fetched
automatically with "make fetchindex".
