We leverage Selenium for our website UI automation test. We establish a lab of 10 machines installed Windows 7 as the only OS. And the automation tests (>800) would be dispatched to those machines evenly once each day. However, we come across below time-out error intermittently among different test cases. At the first glance, it seems to due to timeout when trying to loading and rendering the page. However, when we manually open that page, we never experience that before.
I read through several posts both on the google group and this site, but none of them provides a workaround for my problem. Basically, I am seeking a better way to troubleshoot this timeout exception to find the clear RCA and fix it once for all. I am expecting some switch or verbose logs we can go through. Of course, other suggestions or solutions are appreciated as well.
Below is the timeout error details. You can find version and environment information there.

A closer look at the logs reveals the following about your Test Bed :
Selenium Version : 2.39.0Chromedriver Version : 2.33Chrome Version : 61.0I would suggest you to bump up the Selenium Version to v3.6.0 as in Selenium 3.x a lot of functionalities have been added/upgraded/deprecated with respect to Selenium 2.39.0. Once you are on the recent releases debugging becomes easy for the SO volunteers.
A closer look at the error depicts java.lang.AssertionError and org.openqa.selenium.TimeoutException at the same time. I am sure you must be using either JUnit or TestNG for assertion. The first and foremost step would be to cross check the Java version & Junit/TestNG version compatibility. Finally, the TimeoutException compells me to cross check the availability of a certain parameter which is passed as an input argument for Assertion/Validation.
