Process hangs on spring

[alexevanczuk]

We're seemingly randomly getting process hangs when running things that boot the rails environment. It is easily resolved by just killing the process with ctrl+c and then starting it again... sometimes I need to spring stop?

I used rbspy to take a snapshot of the process while it's hanging and got this:

$ sudo rbspy snapshot  --pid 15173

We're using ruby 3.3.5 and rails 7.2.2

Any tips on what's going on here?

Can you see if you can reproduce it by editing the Gemfile to cause spring to restart? I suspect that's what causes a similar issue for me

Hey sorry @DTrejo , we ended up removing spring due to this and related issues. But let me know if you find a solution!
