NIP: host memory high

Alert: NipHostMemoryHigh · Severity: Warning

What this means

Available memory below 15% (usage >85%) for 3+ minutes.

Business impact

• Risk of OOM kills on containers — see container OOM.
• EasyPay outward has fired this in production.

Confirm

free -h
docker stats --no-stream
dmesg | tail -20 | grep -i oom

Fix

1. Find memory hog: docker stats --no-stream | sort -k4 -hr.
2. Restart leaky container if identified (coordinate if web).
3. Prune unused Docker resources if disk/memory pressure combined: docker system df.
4. Do not blindly restart postgres without app team approval.

Escalate if

OOM events occur or memory stays critical after restart.
