Was a gotop user. Saw it was no longer maintained. Decided to try this. Crashes within three seconds or so.

I can confirm I am also having this issue, it crashes after 10-30 seconds for me.

Also using iTerm and tmux. macOS Catalina 10.15.4. Using ytop version 0.6.1.

I am having this issue with Alacritty and tmux. macOS Catalina 10.15. ytop version 0.6.2.

I just got ahold of a mac to try and reproduce this and didn't have any luck. If any of you all can still consistently reproduce this could you build with debug info and run with RUST_BACKTRACE=full that would really help out for trying to track it down.

Thanks for the backtrace, but the debug info has been stripped. If someone wouldn't mind rebuilding the program with debug info then that would really help. It would require cargo to build and will require adding

[profile.release]
debug = true

To the bottom of Cargo.toml. From there you can run it with RUST_BACKTRACE=full cargo run --release

I was able to find the source of the problem and reproduce it on a friends mac. Ill be opening a pull request later today to fix it, so no need for debug information.

[CosmicHorrorDev]

I've opened rust-psutil/rust-psutil#80 to address this issue, but we have to:

1. Wait for the PR to get merged
2. Wait for a new release of psutil
3. Update the psutil and Cargo.lock file here

So it'll still be a while before this is fully fixed.

Thanks @LovecraftianHorror !

Thanks @LovecraftianHorror. This is also affecting htop as well it seems.

What are y'all using in the meantime?
