I’m new to NixOS, already rebuild 14 times, but now, system just stop/freeze my pc when I try to rebuild NixOS. I’m delete all generation before 11, reboot, and nothing happen: on rebuild freeze, stopped all processes.
That’s RAM, not disk space. It means one or more of the following:
- You’re not following a channel that is built by hydra (instead, e.g.
masterorrelease-*) - Your tmpfs is in RAM rather than on disk, as set by default
- You’re evaluating many nixpkges
- You have a ridiculous amount of browser tabs and chrome clones open
- You have a very under-resourced system
Without seeing your configuration.nix (and potentially related files and nix-channels), it’s hard to tell you which of these apply.
Yeah, I have ~1650 pkgs
Also:
[romchik@nixos:~]$ nixos-version
25.11.6561.1267bb4920d0 (Xantusia)
and channel has:
nixos nixos-25.11 release nixos-25.11.7346.44bae273f9f8
How can I show configuration.nix?
Pastebins, sourceforges, paste here in code block. There are plenty of options.
Also please share some specs of your computer, like CPU and RAM.
I fix the issue, just remove telegram-desktop in pkgs, but it used to work for me, just a week ago I installed it and everything was fine, but now it installs a lot of packages and interferes with the build.
Also my configuration.nix:

Right, that’ll explain it. The build for that specific package is currently failing, which means it’s not cached in hydra.
If you ask nix to build a package that isn’t cached, it will try to build it locally. In the case of telegram-desktop, that’s a pretty big build because it’s basically a skin for chrome, which means you’ll be building chrome which can easily take tens of gigabytes of memory and a lot of processing power.
There’s not much you can do about this, occasionally this will just happen if you use those packages.
Electron packages suck for a bunch of other reasons too, like memory use, and even security, since they’re usually relatively outdated versions of chrome that aren’t sandboxed as well. It’d be nice if electron could die already.
Personally, to avoid this, I just use the web versions of these kinds of applications in a normal browser.
I even wrote a wrapper to make them look like separate applications.
