My bad. These files only show up when one is running a bridge/relay/exit
node. The majority of my work with Tor is setting up and running exit
nodes, so I'm in the habit of thinking about installations in that
light. These files won't show up if you're only accessing the Tor
network as a client.

Based solely on the two errors I've seen from your logs, I can only
guess that there is either some sort of permissions issue (which could
include a rogue process, possibly Tor itself, changing permissions while
Tor is running), or that some process is accessing the lock/state files
and preventing Tor from interacting with them properly. I chose the
"nuke the unnecessary files" approach first because if it worked, it'd
be the quickest and easiest fix. The slightly-more-involved approach
would be checking permissions, etc. The pain-in-the-ass approach would
be rooting around in your system trying to find out what's going on,
filing bug reports, etc etc.
I tend to start with the quick & easy attempt at fixing the problem
because I'm exceedingly lazy =)
