Why Does My Selenium WebDriver Get a \'Session Deleted Because of Page Crash\' Error?

WebDriver Exception: Unknown Error: Session Deleted Because of Page Crash

Selenium users may encounter a confusing error message while using ChromeDriver:

unknown error: session deleted because of page crash
from unknown error: cannot determine loading status
from tab crashed

This error results from a crash in the Chromium web engine underlying the Chrome browser, typically triggered by limited resources or specific system settings.

Solution:

To resolve this issue, several solutions are available:

• Add Chrome Options:

  • chrome_options.add_argument('--no-sandbox')

• Increase /dev/shm Size:

  • sudo mount -t tmpfs -o rw,nosuid,nodev,noexec,relatime,size=512M tmpfs /dev/shm

• Share /dev/shm via Docker:

  • -v /dev/shm:/dev/shm

• Disable Dev Shm Usage:

  • chrome_options.add_argument('--disable-dev-shm-usage')

Additional Note:

The error message "from tab crashed" is related to a Chrome issue in which the system attempts to use /dev/shm for non-executable memory. The underlying fix is included in Chrome v65.0.3299.6.
