I was facing the same issue but was able to resolve.

  • Php path which cron was using was incorrect, hence absolute path should be used.
  • Memory limit for PHP-CLI and PHP was different, so passed the params to override in CLI.

  • Example:

    
*/5 * * * * /opt/lampp/bin/php -d memory_limit=2G /opt/lampp/htdocs/magento/enterprise/bin/magento cron:run | grep -v "Ran jobs by schedule" >> /opt/lampp/htdocs/magento/enterprise/var/log/magento.cron.log

*/5 * * * * /opt/lampp/bin/php -d memory_limit=2G /opt/lampp/htdocs/magento/enterprise/update/cron.php >> /opt/lampp/htdocs/magento/enterprise/var/log/update.cron.log

*/5 * * * * /opt/lampp/bin/php -d memory_limit=2G /opt/lampp/htdocs/magento/enterprise/bin/magento setup:cron:run >> /opt/lampp/htdocs/magento/enterprise/var/log/setup.cron.log

/opt/lampp/bin/php : My PHP path.

/opt/lampp/htdocs/magento/enterprise/bin/magento : My Magento CLI path

memory_limit=2G : Memory limit set to 2G, you can update to it as your server limits.
