Why Does InstaPy Fail with \'cannot determine loading status from tab crashed\' and How Can I Fix It?

Unable to Determine Loading Status from Tab Crashed

Problem:

When using InstaPy, a Python and Selenium-based program, users sometimes encounter the error "unknown error: session deleted because of page crash from unknown error: cannot determine loading status from tab crashed."

Error Message:

ERROR [2018-12-10 09:53:54] [user]  Error occurred while deleting cookies from web browser!
b'Message: invalid session id\n  (Driver info: chromedriver=2.44.609551 (5d576e9a44fe4c5b6a07e568f1ebc753f1214634),platform=Linux 4.15.0-42-generic x86_64)\n'

Possible Reasons:

• Small size of /dev/shm in Docker containers
• Chrome crashing due to insufficient memory

Solutions:

• Add --no-sandbox Argument:

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

• Fix Small /dev/shm Size:

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

• Share Host /dev/shm:

-v /dev/shm:/dev/shm

• Disable /dev/shm Usage:

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

Additional Notes:

• This error relates to a Chromium issue where Linux attempts to use /dev/shm for non-executable memory.
• The fix was implemented in Chrome version 65.0.3299.6.
