Symptoms

An agetty error message is output to the /var/log/secure log fil every 10 seconds while the instance remains on: agetty[<process_id>]: /dev/tty0 ttyS0: No such file or directory.

Impact

This may fill the /var/log/secure log file. When /var/log is full, certain system services may degrade or become unresponsive (e.g., DNS).

Conditions

This agetty error message is an issue on all BIG-IP Virtual Edition and Cloud instances. It is not configuration-dependent.

Workaround

Manually extend the /var/log logical volume. For more information, see Increase disk space for BIG-IP VE :: https://clouddocs.f5.com/cloud/public/v1/shared/disk_space.html.
