Session id invalid when running tests in more than 16 containers

[success-stha]

We are getting invalid session id while running tests in more than 16 containers. The tests run fine when there are less than 16 containers.

Error: org.openqa.selenium.NoSuchSessionException: invalid session id

Machine Specification:

• RAM : 64 gb
• CPU: 56 core
• Model: Intel(R) Xeon(R) CPU E5-2680 v4 @ 2.40GHz
• OS: Red Hat Enterprise Linux Server 7.7

Here is out Browser.json

{
 "MicrosoftEdge": {
        "default": "88.0",
        "versions": {
          "88.0": {
            "image": "browsers/edge:88.0",
            "port": "4444",
            "volumes": ["/opt/docker/fileDownloadLocation:/home/selenium/Downloads","/opt/docker/selenoid/logs/:/opt/selenoid/logs/"],
            "path": "/",
            "shmSize": 2147483648,
            "tmpfs": {"/tmp": "size=2048m", "/var": "size=1024m"},
            "mem" : "2048m"
          }
        }
      }
}

@success-stha seems to be Chromedriver issue. E.g. https://stackoverflow.com/questions/56002701/selenium-webdriver-error-invalid-session-id

while we didnt saw this issue with Chrome 98.0 , we start seeing it again with 99.0+ . anything we can check further?

@Dor-bl probably could be also related to increased /dev/shm consumption. Try to increase shmSize parameter in browsers.json.
