Known Affected Versions:

Opened: Aug 08, 2019 Severity: 2-Critical
After upgrading to v15.0.x, the system cron daemon is not running, which causes periodic system operations not to run. This includes, but is not limited to: -- SSL/TLS ephemeral key generation. -- Log rotation. -- SSL certificate.
The crond daemon is down, making any process dependent on crond to not work on the system: -- The SSL connection mirroring does not work as expected. -- Script scheduling does not work.
Upgrade BIG-IP system from pre-v14.1.0 to 15.0.x.
Enable and start crond: 1. systemctl enable crond 2. systemctl start crond
The system now ensures that the cron daemon (crond) is running consistently after upgrades.
