Serena index crashing and terminating at 82% wins wsl

[visioncourse]

Windows WSL Ubuntu. I've had Serena running ok in the past, but recently tried to index, and it just terminates and crashes the terminal.
I have to reboot windows as it close out all open terminals or vscode terminal i have open.

I have run Serena project index --log-level DEBUG
And here are the results. The last line is before it terminates on the terminal.

Restarted the computer and reran index again:

Not sure if if helps too but if i run

uvx --from git+https://github.com/oraios/serena serena project index-file mcp-server/node_modules/typescript/lib/_tsc.js
it sometimes terminates the window or just returns after a few minutes to prompt.

[MischaPanch]

It's indexing node_modules, are they in your gitignore? The LS itself should know to ignore node_modules though, so is a double failure.

We recently did some improvements to handling of ignores, maybe a bug crept in there. @opcode81 fyi

[MischaPanch]

The LS seems to be unable to index that particular file, maybe too many symbols or something like that. But it should not try to index it at all, I think

Here from my log dump on the indexing showing its process my gitignore:
