## Immediate Emergency Fix

```bash
# Instant relief - run immediately when services are crashing
ulimit -n 65536
echo 2097152 | sudo tee /proc/sys/fs/file-max
```

## Emergency Service Recovery

```bash
# Restart crashed services
sudo systemctl restart docker traefik
sudo docker system prune -f
```

## Check Current Status

```bash
# See what's using FDs
lsof | wc -l
cat /proc/sys/fs/file-nr | awk '{printf "FDs: %d/%d (%.1f%%)\n", $1, $3, ($1/$3)*100}'
```

## Deploy Full Solution

```bash
sudo ./scripts/set-ulimits.sh
sudo systemctl enable --now fd-monitor.timer
```

## Emergency Cleanup

```bash
./scripts/fd-cleanup.sh
```
