Description of the Issue

Experiencing ERR_INSUFFICIENT_RESOURCES errors on backend service despite healthy metrics. Started Jan 27, 2026 at 11:16 AM CST during deployment.

Status:

• Frontend: Working

• Database: Healthy (11/100 connections)

• Backend: Rejecting all API requests with ERR_INSUFFICIENT_RESOURCES

Metrics:

• RAM: 250 MB / 512 MB (50%)

• CPU: 0.1 vCPU

• PostgreSQL: 11/100 connections

• Connection pool: max 10, min 2, idle timeout 30s

Backend shows "Active" status but rejects all incoming requests.

Database Status (verified locally):

Max connections: 100
Current: 11 (11%)
Status: HEALTHY

Code

Database Pool (backend/src/config/database.js):

javascript

const pool = new Pool({
  max: 10,
  min: 2,
  idleTimeoutMillis: 30000,
  connectionTimeoutMillis: 10000,
});

Server (backend/src/server.js):

javascript

const app = express();
app.use(cors({ origin: process.env.FRONTEND_URL }));
app.use(express.json());
app.listen(PORT, '0.0.0.0');

Stack:

• Node.js + Express

• PostgreSQL (pg@8.11.3)

• Railway Hobby Plan

• 3 services: Backend, Frontend, Database

Questions:

1. Could deployment overlap (old shutting down + new starting) cause resource exhaustion?

2. Is there a Railway infrastructure limit we're hitting despite available resources?

3. Any Node.js configuration recommendations for Hobby plan?
