Why is jruby / selenium dropping my connection to my browser

Question

I'm in the process of doing software upgrades and I'm having issues where my tests will start to run, but then all of a sudden the browser will stop responding and I get the following stack trace:

I'm using cucumber (1.3.10), gherkin (2.12.2-java), page-object (0.9.5), watir-webdriver (0.6.6), and selenium-webdriver (2.39.0) with firefox and with chrome with Ruby 1.9.3

I was not having the issue before using cucumber (1.2.3), watir-webdriver(0.6.2) and selenium-webdriver(2.34.0) with ruby 1.8.7

Unable to establish loopback connection

I ran across this problem once based on some other software on my machine blocking JRuby from running these tests. I found out that McAfee Host Intrusion Prevention seemed to be dropping connection to Selenium when I used JRuby but not regular Ruby.

To check if the service is running, as a system admin go to Control Panel -> Administrative Tools -> Services and see if McAfee Host Intrusion Prevention is listed as Started.

If it is, run net stop "McAfee Host Intrusion Prevention Service" in a command prompt window as an admin. After that completes run a test and the test should complete.
