Because stress testing brought a big burden to node machine, so it might occupied too much CPU & Memory in node machine, make node machine can't create driver successfully.
So change the c:\grid\service\watchdog\watchdog.config file, change run_time to 5, default is 15. And delete watchdog.log file.
netstat -na (check connection situation)Problems we might found:
org.openqa.selenium.remote.SessionNotFoundException: Unexpected error launching Internet Explorer. Could not get document from window handle
chrome crash
Solution: kill all related processes, clean the temp folder, restart selenium node service
