What did you do?

Start gopls in a mono-repo and begin working

What did you expect to see?

gopls should function properly within a mono-repo. Memory and CPU usage should plateau and no longer climb and slow down the entire machine

What did you see instead?

go and gopls climb in memory and CPU usage till the point I must completely close and restart all go/gopls instances. This is within a single mono repo that is using vs 1.15.7 but is reproducible on the latest gopls and go version.

@TheSecEng: Can you please follow the troubleshooting guide here and share your gopls logs? Also, please take a look at the memory section of the troubleshooting guide and include those zips if you have them.

@stamblerre I did the logfile command, however it just logs the LSP commands. And that contains private code that I can't just post here. What are we looking for exactly?

Also, my TMPDIR has this in it

If you can redact out the private pieces of information, it would still be helpful to see. gopls usually logs errors and other useful information. One way to share less information might be to share the output of gopls -v version and the output of gopls -rpc.trace -v check path/to/file.go for a file in your workspace.

The nonames files are redacted, so if you're willing to share one of those zips we can take a look at those too.

Timed out in state WaitingForInfo. Closing.

(I am just a bot, though. Please speak up if this is a mistake or you have the requested information.)
