Selenium hangs from firefox. (?)

I'm having this problem with both selenium 3.40 and 3.39 (I don't know what about previous versions).

After a time period that selenium is running (and executing) my test stuck and fail on "find element" and throws the following exception:

OpenQA.Selenium.WebDriverException: The HTTP request to the remote WebDriver server for URL http://localhost:7055/hub/session/44f53200-6259-4f38-8738-b4beda40429f/elements timed out after 60 seconds. ---> System.Net.WebException: The operation has timed out at System.Net.HttpWebRequest.GetResponse() at OpenQA.Selenium.Remote.HttpCommandExecutor.CreateResponse(WebRequest request) --- End of inner exception stack trace --- at OpenQA.Selenium.Remote.HttpCommandExecutor.CreateResponse(WebRequest request) at OpenQA.Selenium.Remote.HttpCommandExecutor.Execute(Command commandToExecute) at OpenQA.Selenium.Firefox.Internal.ExtensionConnection.Execute(Command commandToExecute) at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters) at OpenQA.Selenium.Remote.RemoteWebDriver.FindElements(String mechanism, String value) at OpenQA.Selenium.Remote.RemoteWebDriver.FindElementsByXPath(String xpath) at OpenQA.Selenium.By.<>c_DisplayClasse.b_d(ISearchContext context) at OpenQA.Selenium.By.FindElements(ISearchContext context) at OpenQA.Selenium.Remote.RemoteWebDriver.FindElements(By by)

This issue is a matter of how long selenium is running: When running a test alone, it does not happen. But when I run a test as a part of many tests, it happens.

A call that comes after a one which fails can succeed.

Happen also with chrome. I tried going back so Selenium 2.34 and the problem still exist.

I found it: I set 

WebDriver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(60));

somewhere in my code, this causes every element lookup to wait for 60 seconds for the element to appear.

According to your confirmation, I can say that you are getting this issue because your WebDriver object is static. You can run your tests fine one by one, but once you try to run multiple at a time, the JVM considers your different tests to have the same WebDriver object! Funny, huh..

Find a way to remove the static modifier from your object, which will most likely require you to change your entire structure, and it WILL fix your issue.
