Symptom & Impact

journald drops messages under burst on CentOS Stream 10 disrupts services and slows incident response until the root cause is resolved.

Environment & Reproduction

Burst rate limiter discards container stdout entries during incident replay.

journalctl --disk-usage
cat /etc/systemd/journald.conf
journalctl -u systemd-journald -n 100

Root Cause Analysis

Misalignment between logging configuration and CentOS Stream 10 defaults causes the failure path described above.

Quick Triage

Confirm package state, service status, and recent changes before deeper diagnostics.

systemctl status
rpm -qa | grep -i 
journalctl -p err -b --no-pager | tail -100

Step-by-Step Diagnosis

Capture detailed logs, configuration deltas, and runtime state to isolate the failing component.

journalctl --verify
systemctl status systemd-journald
grep RateLimit /etc/systemd/journald.conf

Solution – Primary Fix

Apply the targeted configuration change and restart the relevant services to restore expected behavior.

sudo sed -i 's/^#RateLimitBurst=.*/RateLimitBurst=20000/' /etc/systemd/journald.conf
sudo sed -i 's/^#RateLimitIntervalSec=.*/RateLimitIntervalSec=10s/' /etc/systemd/journald.conf
sudo systemctl restart systemd-journald

Solution – Alternative Approaches

Ship logs to a dedicated rsyslog or vector pipeline for retention.

Verification & Acceptance Criteria

Validate the fix with deterministic checks and ensure no regressions in dependent services.

journalctl -f
journalctl --disk-usage

Rollback Plan

Revert configuration and restart services to return to the previous known-good state.

cp /etc/systemd/journald.conf.bak /etc/systemd/journald.conf
systemctl restart systemd-journald

Prevention & Hardening

Right-size SystemMaxUse and ship logs off-box for compliance.
