Hi everyone,

Every second I get info from a messaging service (XMPP) and I need to store this info in my database.

Here is my code:

function updateFeux(feuxList) { //feuxlist.lenght = 2000
  let startTime = new Date()

  for (let i = 0; i < feuxList.length; i++) {
        where: {
          id_carrefour: feuxList[i].id_carrefour,
          id_feu: feuxList[i].id_feu,
        data: {
          feu: feuxList[i].feu,
        i == feuxList.length - 1
          ? logInFile(
              'FEU : ' +
                feuxList.length +
                ' ROWS ARE BEIN UPDATED IN : ' +
                Math.abs((new Date().getTime() - startTime.getTime()) / 1000) +
                ' SECONDS',
          : '',

But after a while I get this error:

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The 
promise rejected with the reason:
KnexTimeoutError: Knex: Timeout acquiring a connection. The pool is probably full. Are you missing a .transacting(trx) call?

My technical director told me that this error occurred when we opened too many connections to postgres, I tried in “database.js” to increase the value “max” in the object “pool” but it does not work.

So I thought about it and I say to myself when in reality it has not finished doing the update that I re-call my “updateFeux()” function, is that right?

How I can solve this ?
