Cannot contact : java.nio.channels.ClosedByInterruptException while using GeckoDriver and Firefox

I'm running tests using: Selenium 3.11 Geckodriver v0.20.1 TestNG 6.9.8 Firefox 57 on Linux OS

I have 10 suites with 10-30 classes in each. Total duration time is about 16 hours. Webdriver gets created in beforeClass and get's quit in afterClass (using driver.quit()).

When I run tests using Chrome Driver, everything is okay and all the suites are executed completely.

But if I switch the driver to Firefox driver, only 3-4, or 5 suites are executed, and then I receive the following error: 

Cannot contact : java.nio.channels.ClosedByInterruptException
Can't take a screenshot: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:14191

It appears in different steps and actions, the test just goes regularly and then this error appear:

I added memory info output but seems like there are still enough resources for JVM: 

OS: Linux
    Version: 3.10.0-514.el7.x86_64 amd64
    Available processors (cores): 8
    Current directory: /var/lib/jenkins/jobs/ExaCLOUD_UI_tests_pipeline/branches/feature-E.6pdikdaolhhr.IE-Chrome/workspace/ExaTAGS/TagsRunner

    Currently allocated to the JVM: 2,249.5 Mb
    Free memory in JVM: 1,257.568 Mb
    Used memory in JVM: 991.932 Mb
    Max memory the JVM could reach: 3,250 Mb
    Total free memory: 2,258.068 Mb

    File system root: / 
    Total space: 102387.98046875 Mb
    Free space:30855.1953125 Mb
    Usable space: 30855.1953125 Mb

My question is: where to look for and what to add to debug info to investigate the reason of this happening?

This error message...

Cannot contact : java.nio.channels.ClosedByInterruptException
Can't take a screenshot: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:14191

...implies that a checked exception was received by a thread when another thread interrupted it while it was blocked in an I/O operation upon a channel.

ClosedByInterruptException Class

ClosedByInterruptException is a checked exception which is raised when a thread interrupts another thread while it is busy/blocked in an I/O operation upon a channel. Before this exception is thrown the channel must have been closed.

It is worth to mention that, channel operations are pretty much bound to the thread doing the I/O operations. If this thread is interrupted the stream or the channel is closed due to IO safety issues.

Your code trials would have given us some more hints about what's going wrong but from the error stack trace it is evident one of the major issue is the incompatibility between the version of the binaries you are using as follows:

  • Though you are using Selenium v3.11.0 but your JDK seems to be v1.8.0_45 which is pretty older.

Solution

  • Upgrade JDK to recent levels JDK 8u171.
  • Upgrade Selenium to current levels Version 3.12.0.
  • Upgrade GeckoDriver to GeckoDriver v0.20.1 level.
  • Ensure GeckoDriver is present in the specified location.
  • GeckoDriver is having executable permission for non-root users.
  • Upgrade Firefox version to Firefox v60.0.1 levels.
  • Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
  • Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
  • If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
  • Take a System Reboot.
  • Execute your Test as a non-root user.
  • Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.

trivia

If the AUT (Application Under Test) is a multi-threaded application, you should look for interrupt() calls that might interrupt the thread doing the IO operations on the channel. If it is a web-application or some other kind of managed environment, where thread management isn't up to your application (like a Servlet / EJB Container), you should look for thread-safety violations. Another place to look is when the application is shutting down or when thread pooling is used (Servlet/EJB Container!). Then be aware of dynamic management of the pool size!
