A lot of users have come across failed rebuilds recently (since September 2024) with the command was killed with SIGKILL error, even though the servers have more than 1 GB RAM (even 4 GB RAM). https://meta.discourse.org/search?q=%22command%20was%20killed%20with%20SIGKILL%22 Advice has been given t…

[image] Canapin: Either the requirements have changed, in which case the documentation should be updated, or there’s something wrong. Agreed. Though the setup for the VM i was using really should have some swap, the machine should have had more than enough RAM to handle the build. Maybe just …

[image] gerhard: discourse-setup offers to create a swap file automatically if it detects 2GB or less of memory. This seems to need to be increased. As @Canapin pointed out with my topic having 4g of ram was not sufficient. And as I mentioned in my topic the instructions for adding a swap f…

@david recently worked on this space, our memory bottleneck is during asset compilation and we now have a low memory mode as well. My understanding is that 2gb should still be supported, this is something we will investigate.

Closing in favour of: [image] High rebuild memory requirements: April 2025 edition Self-hosting We just landed this commit which should hopefully improve the situation. Please let us know how you get on! (it’ll hit tests-passed in the next ~30 mins) When test…
