Hi,

I've been getting this exception rather often lately. When I try to called selenium.stop() from selenium.py, the whole thing crashes with this error:

error shutting down:

<html>

Does anyone have an idea why this might be happening? I hope someone can help.

Thanks!

Which version of the RC server do you have?

I'm sorry, I am not getting that error anymore. I didn't realize it was a reply to my older question.

As far as I remember, it was happening because selenium was already stopped (because of some error or my previous call to stop()). Calling Selenium when it's already stopped was throwing out that error.

Thanks,

Neha
