I’ve been getting this error when rebuilding, I have no idea what to do.

I think error code 137 is not enough memory.
Do you have a swap file set up? You can check by running `free` on the command line.
Alternatively, you could upgrade and add more RAM?
One I haven’t tried yet but have read a few times on here is adding `vm.overcommit_memory = 1` to /etc/sysctl.conf
**Edit:** This is from a different-but-similar topic, and has the text from the log in:

I do not have a swap file setup, I’ll check on how to do it and get back to you.

I think we may have a How-To for that:

Most cloud virtual machine providers do not set up swapfiles as part of their server provisioning. In particular, upgrading Discourse produces a lot of memory pressure. With a swap file, rather than randomly terminating processes with an out of memory error, things will slow down instead. Having a swap file is a cheap insurance policy that protects you from many other lo…
