Bug Summary and Steps to Reproduce

Bug Summary:

Creating this issue from #10651 discussion.

Company project, private code, complex & huge C++ one.
We get Language Server Crashed. Restarting... in different machines and developers so frequently. This error is easily triggered if we try to execute Show Call Hierarchy, for example, or just hovering in a method name and wait 2-5 minutes. Sometimes we have found that even without doing anything besides opening a file could happen, but not really sure about this last one.

Removing or renaming the c_cpp_properties & reopening the project seems to avoid crashing so easily & frequently.

The file compile_commands.json are huge for all projects in my division: 48MB && ~83000 lines
This file size could trigger other issues, for example is crashing another projects when trying to configure with CMake Tools Extension Issue 3469

1. Snapshot of things working decently (but some submodules or nested folders seems not working, will be back to this)

Steps to reproduce:

1. Snapshot triggering the issue with just hovering in the same function with the c_cpp_properties.json below. In weird ocassions it does not fail, just takes about ~10 minutes and the log shows parsings the files:

Processing folder recursive
Tag parsing file...

Expected behavior:

• Language Server works.
• C/C++ development experience for production & real world projects is neat.

Additional context

Cannot reproduce the crash when attaching. It does not stop anywhere, but the extension or process is killed.

Inizia con la configurazione c_cpp_properties.json segnalata, il compile_commands.json da 48MB e l’output di Debug durante la riproduzione di Show Call Hierarchy o dell’elaborazione attivata dall’hover. Il lavoro è completato quando il server del linguaggio non va più in crash né si blocca sul progetto segnalato, e i log identificano il problema rilevante se il problema persiste.
