Audit logs can consume all available partition space.


Audit data loss when /var/log is full.


Audit logging enabled for a sufficient period of time


You can recover disk space by manually removing unneeded logs in /var/log/audit.

Fix Information

The BIG-IP system periodically checks for free disk space at '/var/log'. If disk usage exceeds configured threshold and when software detects a possible problem with storing audit logs, all important processes are shut down to prevent generation of audit logs. If this occurs, the admin must manually recover the system.
