Cron issues on drupal
Well here are some quick ways of solving your “cron not working properly issues in drupal”
It has a semaphore which blocks the cron running, in my case the PHP script ran for too long and ate up too much memory. I needed to modify my php.ini to ensure that it could take up more memory.
Another issue was that you needed to delete a certain variable in the Drupal database, use the following for a quick resolution to the problem.
DELETE FROM `variable` WHERE name = ‘cron_semaphore’;
DELETE FROM `variable` WHERE name = ‘cron_last‘;
Another way is to install the devel module and delete the above variables from the database using the UI.
Hope this helps.
Thank you for this help. This article really saves my time
