Immediate Emergency Fix

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

Emergency Service Recovery

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

Check Current Status

# 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

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

Emergency Cleanup
