I have similar symptoms. The info column on the hobbit server does not display, apache error log gives me this:

[Wed Jul 23 08:26:28 2008] [error] [client 10.10.10.2] Premature end of script headers: bb-hostsvc.sh, referer: http://hobbitmon.example.com/hobbit/

The info column on all other hosts seem to be fine though.

Stop/start of hobbit has no affect. I'm also using the Snapshot release.

I use FQDN on all hosts.
