Symptom & Impact

Kernel audit queue overflows causing dropped audit events.

Environment & Reproduction

Messages show backlog limit exceeded in dmesg/journal.

Root Cause Analysis

Run auditctl -s and review /etc/audit/auditd.conf and rules.

Quick Triage

Too many broad audit rules or insufficient queue parameters.

Step-by-Step Diagnosis

Increase backlog settings and optimize high-volume rules.

Solution – Primary Fix

Sustain workload test and confirm no dropped-event warnings.

Solution – Alternative Approaches

Regularly prune rules and benchmark audit impact.

Verification & Acceptance Criteria

Restore prior audit rules if compliance profile regresses.

Rollback Plan

Deploy audit rule profiles per role to reduce noise.

Prevention & Hardening

auditctl -s; augenrules –load; systemctl restart auditd

Related Errors & Cross-Refs

Provide rule set, throughput metrics, and kernel messages.
