I am executing my Selenium tests against a Grid server, hosted on a different machine. My grid invocation is (bat file):
cd c:\
start java -jar c:\selenium-server-standalone-2.46.0.jar -role hub -registerCycle=5000 -browserTimeout=60
start java -jar selenium-server-standalone-2.46.0.jar -role webdriver -hub \
http://localhost:4444/grid/register -port 4445 \
-Dwebdriver.chrome.driver=C:\chromedriver.exe \
-browser="platform=WINDOWS,browserName=chrome,maxInstances=" \
-browser="browserName=firefox,maxInstances=1" \
-Dwebdriver.ie.driver=C:\IEDriverServer.exe \
-browser="browserName=internet explorer,maxInstances=1"
(Disregard '\', I'm using this for formatting on StackExchange only. My file is one line).
Some more details....
OS: Win 7 Pro IE Version: 8
Everything works great for the first 25 or 26 tests, and then they all fail after that (approx. 200). If I run these locally, they pass. It's kind of hard to catch, but it seems that when the problem happens, after my call to
Driver.Close();
Thread.Sleep(1000);
Driver.Quit();
... that Grid fails to close the current Internet Explorer handle and then creates a new one. So now, I have two handles open. The most instances of IE I have ever seen open is 3-4.
When I check my node instance after it's finished running, I have the following exception:
20:17:49.725 INFO - Available nodes: [http://172.30.33.246:4445]
20:17:49.741 INFO - Trying to create a new session on node http://172.30.33.246:4445

The goal is to have all of these tests passing when running on the Grid server. And again, they all pass locally while running in IE8.
