Hi All,

I was wondering if anyone could advise me based on the following log when performing an upgrade.

```
Errno::ENOMEM: Cannot allocate memory - gzip -f -c -7 /var/www/discourse/public/assets/docker-manager-app-fc45ae9f5dc46a536ad03487a4ce173f.js > /var/www/discourse/public/assets/docker-manager-app-fc45ae9f5dc46a536ad03487a4ce173f.js.gz

Tasks: TOP => assets:precompile
(See full trace by running task with --trace)

```

I could see its a memory issue. But how to I overcome this?
