**CRITICAL Issues:**
- **Gateway memory pressure CRITICAL** — heap 2.2GB, RSS 2.8GB (exceeded thresholds)
- **Event loop saturated** — 100% utilization, P99 delay ~5s, max 6.5s
- Two concurrent agent sessions consuming resources

**WARNING Issues:**
- **Disk `/dev/md2` at 83%** — approaching 85% warning threshold (1.4T/1.7T used)
- **Load average ~8-9** — elevated but not critical
- **11GB swap in use** out of 33GB

**Action needed:** Gateway restart to relieve memory pressure. Disk cleanup investigation recommended.
