Express post request flood

Question

Introduction

I´ve a nodejs application with express that have some post and get request. The whole website works just fine without problems.

Problem

If I call the post request to much in time the site will crash. It will not respond to other requests. Doesn´t matter if it´s get or post request.

My Code

Client side

It´s a easy post request to set a client permission. There is no callback defined.

$.post(
   '/clients/set/client/permission',
   {
      permName: globPermissionTable[permName],
      value: checked,
      id: '<%= data[0].id %>'
   }
);

---

Server side

Just a easy post segment. Even if I will uncomment all in the request it will be not response.

app.post('/clients/set/client/permission', function(req, res) {
   // Permissioncheck
   /*var permName = req.body.permName, val = req.body.value, id = req.body.id;
   if(helper.checkParams([permName, val, id])) {
         database.SetClientPermissions(parseInt(id), permName, (val === 'true') ? true : false);
   };*/
});
