Thanks Erik and Wancheng, for pointing out the DBMSD bit - it's fixed now.
Two points:

1. You should only run the DBMSD on one machine. The manual says: "One machine should run the condor_dbmsd daemon. On this machine, add it to the DAEMON_LIST configuration variable. All Quill-enabled machines should also run the condor_quill daemon. The machine running the condor_dbmsd daemon can also run a condor_quill daemon."

One question: What do you mean "Quill-enabled machines"? Does it mean all the Execute nodes? If yes, what's the benefit running QUILL on every single node?

The only reason you would run Quill on every single node is if you
are keeping track of all the startd information in quill.  The more
common configuration is only to run on the nodes that have a schedd.
If you are keeping track of all daemon info in quill then you
need a huge database machine, there are some presentations in
condor weeks of 2007 and 2008 that describe just how big.
