My staging server hangs when I rebuild it. Previously it was working OK:

`DEBUG -- : Delivering messages [] to client xxxxxxxx for user 1 (chunked)`  
What would this be?

That would be a debug message. Do you have the entire rebuild session log handy?

I think you are due for a full CLI rebuild…

```plaintext
cd /var/discourse
./launcher rebuild app

```

That’s what I was doing? 🙂

Problem seems to have gone away. I did upgrade the RAM to 2Gb.
