Process hangs on spring #731

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?
