cvsup [stop at Checkout src/UPDATION] FreeBSD 5.3-STABLE

[STAMPA 2]

Hi.

I did a cvsup stable-supfile (ports-all tag=. , src-all) at a FreeBSD 5.1. WORKS PERFECTLY.
but, i did a cvsup stable-supfile (ports-all tag=. , src-all) at a FreeBSD 5.3 and it shows:
OBS: both i used RELENG_5

Connected to cvsup4.FreeBSD.org
Updation collection src-all/cvs
  Edit src/COPYRIGHT
  Edit src/Makefile
  Checkout src/Makefile.inc1
  Checkout src/UPDATING
(after 5min + - the message)
Detailer failed: Network write failure: Connection timed out
Will retry at xx:xx:xx

I 've tryed using:

cvsup -P m (I read at cvsup.org that if I have a firewall, could be the problem...)

Whats the problem?

Thankful
