17.5.1.6, 17.1.3.2
Opened: Jun 12, 2025 Severity: 3-Major
Logs for various modules are stored in the /var/log directory, with older files compressed into tar files over time. When the storage in /var/log exceeds the warning threshold, a cleanup mechanism is triggered to delete tar files and free up space for incoming logs. However, the cleanup process deletes newer tar files first, leaving the oldest tar files untouched.
When the storage threshold is exceeded, BIG-IP initiates cleanup of tar files. However, tar files containing the oldest module logs are not deleted.
This issue occurs when BIG-IP accumulates logs to the point where the /var/log directory surpasses the storage threshold.
Use the command below to delete the old tar files available in /var/log/ directory rm <tarFileName>
A fix has been implemented to ensure that when the /var/log directory exceeds its storage threshold, all tar files, including those containing the oldest logs, are deleted during the cleanup process.
