Hi all :slight_smile: I get some wired ReadOnlyMemoryError on a beefy windows machine. I’m using PyCall to fetch data from Snowflake. Any idea why this sometimes happens? Cheers ReadOnlyMemoryError() Stacktrace: [1] macro expansion @ C:\.julia\packages\PyCall\BD546\src\exception.jl:95 [inli…

const SNOWFLAKE = PyNULL() function __init__() copy!(SNOWFLAKE, pyimport("snowflake.connector")) end function receive( sql_command::String, )::DataFrame result = DataFrame() try ctx = SNOWFLAKE.connect( user = Settings.user(), password = Settings…

That’s not a MWE, it needs to be a self-contained piece of code which reproduces the problem. Please read point 4 again. I’m not being pedantic - giving a MWE makes it a lot easier for people to help you.

You are right!!! But I can’t share the whole thing because it’s from work.

That’s where Minimal gets into the picture. Remove everything that’s irrelevant to causing the error. Once you’re done the problem has either become obvious or small enough that its proprietary nature is no longer a problem.

My guess is ODBC & Windows is involved Try a new connection every time instead of re-using connections and you should see it go away

It’s impossible to help without a MWE, please see point 4 here: Please read: make it easier to help you
