[bschnurr]

looks like its running out of memory Is this a public repo?

you could try increasing memory https://github.com/microsoft/pylance-release/blob/main/TROUBLESHOOTING.md#increase-memory-limit-for-vs-code-remote-only

[SimNine]

@bschnurr it is not a public repo. I thought about increasing memory, but the issue actually seems to be that memory usage keeps increasing constantly (and indefinitely), even when nothing new is being indexed or opened, and therefore the process will eventually run out of memory no matter how much is allocated. My issue actually looks to be the same as https://github.com/microsoft/pylance-release/issues/7400, so I will mostly continue corresponding there
