Angular Language Server crashes very frequently

For my work I am currently using Webstorm with Angular on a monorepo. 

The monorepo has been growing bigger during the last few months, and recently the performance of the ALS has been degrading heavily, whether it's modifying just a single minimal .component.ts or some big one. For example, when I add a new line before existing code, then the following line instantly grays out, and WS have to reinfers the variables and methods again. This used to be almost instant but now it takes up to 10s.

After skimming through the log, I can see warnings like this. After enough failures, it just give up and stop inferring types as a whole unless I manually restart the LS.

What other log would be relevant here?
