Rsync problem

Hi Guys does any know the cause of this error on rsync:

tried transferring files to a remote server in a NFS share directory and i got that error, previously it was ok.

What o/s are you on and what version of rsync. What are the contents of what you're trying to rsync? Post the command you're using. Have you tried rsync -vvvv or rsync -vvv?
