Issue
I have selenium based web application developed using spring boot. The server is located as VM Instance of google cloud server.
Please find below the details about the versions.
Spring Boot - 2.0.0.RELEASE
Selenium - 3.9.1
Linux - Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux
Chrome Driver - 2.35.528139 (47ead77cb35ad2a9a83248b292151462a66cd881)
Google Chrome - 70.0.3538.110
JDK - 1.8.0_232
From the past few days, I am facing a strange issue, application works fine when business hours start but after few hours it becomes unstable and whole application stop working, even user can not login. After digging more for this issue I found the below error from server logs. I have to restart the VM Instance in order to fix it.
.
After restart, it works fine for a few hours and then we face same issue again.
Also, I have noticed that while sending an email we face the below issue which works fine before
a few minutes.
I also verified the server resource usage but didn't find any suspicious activity. I googled for this issue but most of the solutions are provided for the problem being faced while running it first time. However, in my case it works fine for few hours and then start having this issue.
Please help me to understand the issue and root cause of this problem. It would be better if you can suggest a solution as well.
Thanks in advance.
Solution
This error message...
java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:1731
...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser session.
Your main issue is the incompatibility between the version of the binaries you are using as follows:
- You are using chromedriver=2.35
- Release Notes of chromedriver=2.41 clearly mentions the following :
Supports Chrome v62-64
- Presumably you are using chrome=70.0
- Release Notes of ChromeDriver v2.44 clearly mentions the following :
Supports Chrome v69-71
- Your Selenium Client version is 3.9.1 which is almost 2 years older.
So there is a clear mismatch between Selenium Client v3.9.1 , ChromeDriver v2.35 and the Chrome Browser v70.0
Solution
Ensure that:
- Selenium is upgraded to current levels Version 3.141.59.
- ChromeDriver is updated to current ChromeDriver v79.0.3945.36 level.
- Chrome is updated to current Chrome Version 79.0 level. (as per ChromeDriver v79.0 release notes)
- Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
- 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.
- Execute your
@Testas non-root user.
