High memory usage in 0.3.40(memory leak?) #1298
Description
The fixed implemented in #832 worked for some releases, but I'm having again high memory usage problems (10gb+) with version 0.3.20
These seems to be due to a memory leak: if finishes analyzing the project without problems, using less than 1gb in my case. After working on the project for some time it starts using more memory, even more than 10gb+.
I've not kept note of the details regarding after how long or if there is an action that triggers it. I usually notice a slow down, check the task manager and usually the language service is using many gb of memory. I have not kept track to see it the increase in memory usage is sudden or more gradual.
Below are the packages of the project used and some system information. I haven't checked if I can reproduce this issue in other projects
Is there some logging or telemetry I can enable to help with this issue?
