WHMCS cron error: mmap() failed:  Cannot allocate memory

You may receive the below email regarding the failure of the daily WHMCS cron job
This is because the daily WHMCs cron job under /home/username/whmcsdata/crons/cron.php is scheduled to run every 15 minutes. We have a maximum memory_limit of 256 MB on our shared servers per account. The WHMCS cron performs a number of activities. The memory footprint of the cron can be lowered by skipping the WHMCS update check. You may modify the command to the below mentioned command:
php -q /home/username/whmcsdata/crons/cron.php -vvv skip --CheckForWhmcsUpdate
This can be done from cPanel>Advanced>Cron Jobs>Navigate to the above cron job>Edit.

You can check for WHMCS updates manually from Utilities>WHMCS Update and clicking the Check for Updates button.
For any further queries, you can contact our 24/7 support team through the desired channel.
