I have a function, that terminates fine if I run it.

```julia
f() # terminates after ~10s

```

However if I profile it, it does not:

```julia
using Profile
@profile f() 

```

CPU usage goes down to 0% after a few seconds while and the function does not terminate anymore. Also, I cannot interrupt using CTRL+C.

Is this something people have run into before? Any ideas on how to approach this?

Hard to say what’s going wrong without knowing what `f()` is doing. Slower execution during profiling is expected, but it shouldn’t stall outright.

Do you have a reproducible example you can share?

No, sadly I am far away from having an MWE, just wanted to check if this is a known phenomenon, before deciding to put effort into this.
