Java heap space error caused by ApexIndexer

Hello,

Unfortunately the same issue as #1103 is still exiting. I’m unable to load the @isTest panel and the code completion is not working. Here is the complete log generated when I tried to run a test from VSCode for example:

@ntotten Carrying over from the SF Success Community question. The error above is somewhat similar to the ones that we get when opening org that have a very large number of metadata artifacts.

From yesterday when I re-opened a massive-org project … 12:36:54.324 [Apex Prelude Service STARTING] INFO a.j.l.i.s.ApexPreludeManagedService - Scanning built-in and system Apex types.

Hi @AntunBartonicek - You’re right that more memory isn’t a silver bullet and it doesn’t help in all cases. We are still seeing issues when indexing large projects and are tracking on #2410

Thanks…
