Heap memory limit error #142

Closed mohammad7t closed 4 years ago

mohammad7t commented 4 years ago

Thank you so much for providing this great extension. It significantly improves my python development performance. How can I increase the heap memory limit for the extension so that I can prevent the error logged below?

I have tried opening vscode using code-insiders --max-memory 16000 too, but I got the same results.

mohammad7t commented 4 years ago

In order to reproduce, install a bunch of libraries and ctrl+click on a python function inside one of the libraries.

jakebailey commented 4 years ago

@mhsekhavat Have you seen this in more recent builds?

jgkatz commented 4 years ago

I've been seeing similar right when pylance starts with a workspace containing several different python package folders. It goes through several loops of the following, then dies. I've had to uninstall the extension since it fails on every start.

vscode: 1.48.2 pylance: 2020.9.0

heejaechang commented 4 years ago

should be fixed in 2020.9.4

gkaemmer commented 1 year ago

Does anyone know what exactly was fixed here? I am also trying to load a massive python project with Pylance and getting the same error. Maybe @heejaechang ? (sorry I know this issue is extremely old)

The pylance server loads files until it hits 2GB of memory and then crashes with a JavaScript heap out of memory error.

heejaechang commented 1 year ago

so, we added something that will dump caches if memory hit certain threshold. but sounds like it didn't work out as we hope in certain cases.

Can you provide us some logs as described in the troubleshooting guide?

that will give us some idea on how our cache management hook worked.

erictraut commented 1 year ago

Also, please file a new bug. This one was closed nearly three years ago. The problem you're seeing may have similar symptoms, but it's almost definitely not the same underlying issue as this one.
