OpenQA.Selenium.WebDriverException : No response from server for url

[lukeis]

Originally reported on Google Code with ID 3719

When using ChromeDriver via ChromeDriverService and RemoteDriver
and run multiple tests. They _sometimes_ fail with the exception above.

The tests run OK when I start individual ChromeDriver per each unit test.

The stack is as follows:

OpenQA.Selenium.WebDriverException : No response from server for url http://localhost:50258/session/e58704878fbaecee8aaefabe64076eeb/element/:wdc:1334321221530/click

I'm still seeing this with latest chromedriver, grid, and selenium.  

Running tests on the local computer through chromedriver works great, but I run tests
through a grid(on the local machine) the failure rate goes way up - lots of these No
Response exceptions.

I see this error with windows 2003 R2, firefox 13, using webdriver.
it just started occuring recently, for me.

Also with the most recent chromedriver this happens frequently as well
on windows XP sp3 with chrome 20, 21, or 22. i resorted to disabling the updates for
chrome to keep the chrome 20 driver able to work.

I've read elsewhere that it may be a request limit (for proxy servers having too low
of a conection limit), that causes the server to return null and crash with the "No
response from server for url" exception. 

The "No response from server for url" exception seems to occur whenever a request by
the server returns null or an empty response at which point the server crashes.

It Might be a load related issue, as in when the load of requests is too much for the
drivers to carry, then they throw the  "No response from server for url" exception

All my tests broke today with the following error

OpenQA.Selenium.WebDriverException : No response from server for url http://localhost:7057/hub/session/283a5d58-82dd-483b-a3ef-0ff3ee37841c/element

Am on WebDriver C# bindings 2.25.1 Win 7,FF 14/13

They all worked fine until early today nothing has been changed.
However if i rerun them again they work alright a few times.

Are we going to get a fix for this in future releases ?

cheers,
s
