I have a _join_ node configured like this:

![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/4/c/4c4062e522c41aceb38a045d34610fc677adb076.png)

You would expect a maximum of one message every 5 seconds coming from this node, wouldn't you?

But watch what happens:

I made another observation. So far the node _function 4_ was configured like this:

If I change it to this:

Suddenly my _join_ node starts to work as expected:

Ok, this is caused by the `parts` key in the message object, which should have no bearing in manual mode but does. ~~I'll open an issue.~~ I found [an existing issue](https://github.com/node-red/node-red/issues/1957) that seems to be about this exact problem.

I'm not sure you have solved/fixed it or not.

Observations:  
you didn't tell the `join` node how many messages to join.  
But to send the new message after 5 seconds (I think it is seconds) of receiving the first one.

That may be a problem.

What happens if you set the `After a number of message parts` to `5`?

I suspect you accidentally put the `5` in the wrong box.

In the picture you show of `function 4` and how you send the payload.

Shouldn't it really be

```auto
return {
     'payload': 'foo'
};

```

to be more correct as all names in JSON need to be in/between `"` or `'` to work.  
That they do without them is _luck_ and shouldn't be done.

Though that shouldn't cause problems.

If you did find one, well done.

I think you should outline the problem you are trying to solve, then people can assist you in getting there.  
Currently you are observing certain behaviour based on timing and variable/non-consistent input, not so easy to reverse engineer.

There is further discussion of this in the [bug report.](https://github.com/node-red/node-red/issues/1957)
