Hello,
I have a problem on my Debian 13 computer. I bought a new computer for Rust development, so it should be fast: Intel i5-14400, 32 GB RAM.
Once per day or so of working, while I'm running Cargo build, the computer hangs badly enough that I give up and power cycle it, usually after 15 minutes or so.
The computer is otherwise stable; it only hangs while running Cargo build.
I noticed that removing a large include_dir!() from my program reduced the frequency of lockups, but they are still occurring.
I'd hoped updating Rust would fix this, but this happened just now again after I updated from Rust 1.90 to 1.92, so I thought I'd ask.
I have noticed in the system monitor that the lag and hangs are associated with bizarre spikes in disk read, of 1 to 2 GB/sec sustained over many seconds, combined with all-cores CPU usage.
The same project builds OK sometimes, so I think it's probably a bug somewhere.
I have jobs = 6 set in my config.toml.
I wonder if it is a Btrfs bug (my boot drive is Btrfs SSD), but it just happened again after I moved my project to an external hard drive using ZFS. The Cargo package cache is still on the SSD.
Has anyone else seen this? Any idea what I can do to address it?
Thank you.
