[vox-tech] login oddity

Hey all,

I was trying to log into my FC6 system the other day
and was able to do so. However, I attempted to do so
again a few hours later, and was denied access. I've
attached the relevant portion of /var/log/secure

What gives? I double-checked and the firewall settings
were unchanged from one time to the other (near as I
can tell), as was my TCP wrappers scheme. 

Then, the following evening, I was able to log in as

Dec 15 22:25:36 localhost sshd[32762]: Accepted
password for cylar from port 1771 ssh2
Dec 15 22:25:41 localhost sshd[32762]:

What would make PAM lock me out, even temporarily?
