possible bogus kernel error messages

[admin2]

Hi,

These error messages just started appearing in my /var/log/messages file the
other day.  Running FreeBSD 4.7 Stable.  Can somebody explain why this is
happening - that appear bogus to me?

Apr  4 03:14:35 typhoon /kernel: pid 48518 (rsync), uid 0 on
/mnt/da1-root/var:file system full
Apr  4 04:14:35 typhoon /kernel: pid 48783 (rsync), uid 0 on
/mnt/da1-root/var:file system full

but the df -k shows there is 41MB on the /mnt/da1-root/var partition.  I even
umounted and fsck'ed this partition with no errors.

rsync  version 2.5.5  protocol version 26 is being used.

here is the df -k :
