Selenium server (ver. 2) has stopped working for me for unknown reasons (see Selenium (RC) hangs when started from Python test). I'd like to stop Selenium sever and restart it. When I enter "http://localhost:4444/selenium-server/driver/?cmd=shutDown" into the address bar of a browser on the machine running Selenium server, I get a blank screen in the browser window. If I try to wget that address, the command line says no data received. If I run:
ps aux | grep sel
It shows that Selenium server is still running. Any ideas?

If you are using Windows, see if this post helps you:


For UNIX / Linux, find the process Id (PID) corresponding to the selenium server, and kill the process

  • Ah, thanks. Didn't know why I didn't think of that. I finally just started selenium server on another port...
