Opened: Jun 29, 2026 Severity: 3-Major
Scheduled cron jobs that access the ConfD control port fail silently. This also happens to systemd units that access the ConfD control port.
Any cron-driven or systemd unit workflow that invokes the ConfD via 'f5sh/confd_cli/f5_confd_cli' stops working silently except for connection failures in the job's own output.
A scheduled job (cron / system_cronjob_t domain) or systemd unit that connects to the ConfD control port (TCP/4565). For example, anything that invokes one of the following: - /usr/bin/f5sh - confd_cli - f5_confd_cli.
Use the "ssh root@localhost f5sh" command instead of f5sh. Note: This requires the usage of another level of quotes. Instead of using the following command: f5sh "config; system database config-backup name otters.xml proceed yes" Use the following command: ssh -o 'BatchMode yes' -o 'LogLevel error' root@localhost f5sh "'config; system database config-backup name otters.xml proceed yes'"
