Hello,

First time I’ve encountered this issue running Julia on WSL2.

```julia
Julia Version 1.9.1
Commit 147bdf428cd (2023-06-07 08:27 UTC)
Platform Info:
  OS: Linux (x86_64-linux-gnu)
  CPU: 12 × Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-14.0.6 (ORCJIT, skylake)
  Threads: 1 on 12 virtual cores

```

```julia
WSL version: 1.3.11.0
Kernel version: 5.15.90.2-3
WSLg version: 1.0.54
MSRDC version: 1.2.4240
Direct3D version: 1.608.2-61064218
DXCore version: 10.0.25880.1000-230602-1350.main
Windows version: 10.0.22631.1972

```

The JLS was running fine, as usual, then it suddenly crashed and a restart attempt gave the following error messages.

[Error - 6:58:52 AM] The Julia Language Server server crashed 5 times in the last 3 minutes. The server will not be restarted. See the output for more information.

Source: Julia Extension

```

Reinstalling Julia 1.9.1 and the VS Code Julia Extension did not solve the problem.

Also, Julia 1.9.1 loads as expected on Windows 11.

Do you have a file with very deeply nested syntax constructs open in your workspace?

Yes, that does seem to have been the case.

Thank you.

Any chance you can share that? I’m curious what syntax is that deeply nested; we should probably move to a iterative instead of recursive algorithm anyways.

Sorry, that code was an method in my project that proved to be a dead end, so I deleted and replaced it before reading your message.

If I encounter this issue again in Julia 1.9.2 or future versions, I’ll keep your request in mind and save and share the code.
