guys. This error will random appear when I running tests.
Chromium opened a tab, but soon automatic shut itself down quickly, then this error appeared.
I didn't find the answer on the google.
- The error is happens randomly. 
- Error appear probability is higher of multiple tests running. 
- It won't all fail, often the last test will succeed.
