Site advise shows:
> “Sidekiq is not running. Many tasks, like sending emails, are executed asynchronously by sidekiq. Please ensure at least one sidekiq process is running. [Learn about Sidekiq here](https://github.com/mperham/sidekiq).”
Manually trigger jobs in sidekiq seems does not work either( I tried return heartbeat task but looks like it failed.
Also upgrade discourse gives me a blank page forever.
Any suggestion on how to bring my site back to normal?

try a rebuild via the command line and not the web interface

Thanks! I just tried a few commands:
`./launcher rebuild app`
→ Cannot connect to the docker daemon - verify it is running and you have access
`service docker start`
→ return nothing
`docker info`
→ `fatal error: runtime: out of memory`

What information I need or what can I do to further investigate this?

then use sudo to run the docker
`sudo service docker start`

this returns nothing and rerun `./launcher start app` still shows same " `Cannot connect to the docker daemon`" error.
BTW, `free -h` result, I experienced one error update 4 days ago and from that time disk and cpu shows spike metrics.

will I lost all data if I just restart my instance?

Not sure anyone can 100% answer this question, but the only thing todo is a reboot.

For anyone who has the same issue, an instance reboot works for me and RAM/Swap back to normal:

| Swap: | 2.0G | 6.8M | 2.0G | | | |
+-------+-------+------+------+--------+------------+-----------+
```
then I just rerun `./launcher rebuild app` and everything works again, sidekiq starts to work.
