TimeoutError: ResourceRequest timed out at ResourceRequest._fireTimeout

What are you doing?

Trying to run basic CRUD operations

{
    "username": "localhost@arun",
    "password": "",
    "database": "test",
    "host": "localhost",
    "dialect": "mysql",
    "pool": {
      "max": 5,
      "min": 0
    }
  }

What do you expect to happen?

Run the code without any errors.

What is actually happening?

Server starts normally. After a few calls to the APIs, it stops the server and displays the following issue:

{ TimeoutError: ResourceRequest timed out at ResourceRequest._fireTimeout (C:\Users\arun-awnics\Documents\workspace\node-samples\mm-node\node_modules\generic-pool\lib\ResourceRequest.js:58:17) at Timeout.bound (C:\Users\arun-awnics\Documents\workspace\node-samples\mm-node\node_modules\generic-pool\lib\ResourceRequest.js:8:15) at ontimeout (timers.js:475:11) at tryOnTimeout (timers.js:310:5) at Timer.listOnTimeout (timers.js:270:5) name: ‘TimeoutError’ }

Dialect: mysql Dialect version: 2.15.0 Database version: 10.1.24-MariaDB Sequelize version: 4.22.5 Tested with latest release: No

Hi @sushantdhiman

I spoke with @mickhansen yesterday in slack and resolved this issue. I was using transactions in my GET methods but didn’t manage them properly. Hence the pool was getting filled with transactions and causing the issue.

return sequelize.transaction().then(function(t) {
            userModel.user.findAll({ transaction: t }).then((user) => {
                callback(user);
            });
        });

Now I changed my code to look like this(without transactions):

userModel.user.findAll().then((user) => {
            callback(user);
        });

It works fine now. You may close the issue. Thank you for your time.
