FreeBSD 10.0-RELEASE-p7 amd64

My system log is filling up with the following messages:

That is only a short except of them. I asked on the FreeBSD forum regarding this problem and they said it is related to "denyhosts". I have no idea if this is a serious problem, it would appear to be so since sshd is exiting, or if it can be safely ignored.

This is line 25:
sshd : /etc/hosts.deniedssh : deny

I can supply the config file if you need it. "denyhosts" was installed via the FreeBSD ports system, version (2.6.5).

Thanks!
