Encountered this error while using Selenium with ChromeDriver on Heroku Free dyno.
selenium.common.exceptions.WebDriverException: Message: unknown error: session deleted because of page crash from unknown error: cannot determine loading status from tab crashed
Added these two arguments for Selenium ChromeOptions solved my problem.
This will force Chrome to use the /tmp directory instead. This may slow down the execution though since disk will be used instead of memory.
- "from tab crashed"
Relates to Linux attempting to always use /dev/shm for non-executable memory.
