You need at least 1G of swap space - do you have it?

```plaintext
free

```

will tell you.

Edit: I recommend you read  
[MKJ’s Opinionated Discourse Deployment Configuration](https://meta.discourse.org/t/mkjs-opinionated-discourse-deployment-configuration/193355)  
too. You have this warning which is not good on a small memory system

See the Kernel Configuration section - you need these effects, although whether it’s exactly these commands may depend on which distribution you are running:

> echo 'sys.kernel.mm.transparent_hugepage.enabled=never' > /etc/sysctl.d/10-huge-pages.conf
> echo 'vm.overcommit_memory=1' > /etc/sysctl.d/90-vm_overcommit_memory.conf
> sysctl --system
> 
> ```

Edit: you can check these two important settings on your running server like this

```plaintext
# cat /proc/sys/vm/overcommit_memory
1
# cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]

```
