"SessionId doesn't exist" error when starting Selenium server

I'm raising a Selnium-server (the jar), and getting this exception without trying to talk to the server. What can be the cause? The errors keep coming in once every 2 seconds. Could this be some leftover from a previous Selenium run?

I had the exact same issue and it appeared an mshta.exe process was hanging on the test server. It also consumed an absurd amount of memory (600MB), slowing down the entire server.

Try turning the server off and on again.

I agree with Dave, it must be some application which is trying to connect to port 4444. Just change the port number and see if it helps

Do you have any tests running when you start the server? You could look at any incoming network traffic to port 4444 to find out what's generating the requests. If you can't find who/what is sending the requests you could change the port to something other than 4444 when you start the server.
