I see the following message when starting titan-server: 

Caused by: InvalidRequestException(why:Keyspace names must be case-insensitively unique ("titan" conflicts with "titan"))

Here is how i start it.

~/titan-server-0.4.0$ bin/titan.sh -c cassandra-es start

What am i missing? Thanks for any help.

Of course, After I run 

titan.sh -c cassandra-es clean

and it starts up just fine. Does that mean there was something wrong with my data.

When you do clean you say that it "starts up just fine". Does that mean you've only seen the problem once? Or are you able to easily get Titan Server into a scenario where you can easily recreate it? If you can recreate it, what are the steps to do so? – stephen mallette
Sorry for late reply. I ended up doing 'clean' to see if the problem would go away and it did. I will load the graph again today and see when the problem comes back. But I was having this problem for a while and usually it would take a bounce or two for it to go away and this time it didn't. – sharmami
Update: I am not seeing this issue with titan-server-0.4.1 so far. I will update this thread again if I see otherwise. – sharmami
