This might be caused by recursion over very long tuples or argument lists.

How should I go about debugging this?

[bluesmoon]

Bump. I just updated the message to make it more readable without horizontal scrolling.

[bkamins]

I have never built a system image. Are you trying do do groupby on a very wide table with lots of by?

[bluesmoon]

No, I don't have very wide tables. Probably 15-20 columns at most, and when I do groupby it is with 2-3 columns in by.

Some of the columns are Vector{Vector} if that matters.

[pdeffebach]

Can you make an MWE? I would like to check this out.

[bluesmoon]

I'll try. We have a fairly large codebase and this shows up in my CI logs. Might be easier to find out exactly which version of Julia & DataFrames it started happening.

[bluesmoon]

Ok, so I still can't make an MWE, but I discovered that if I add import_into_main = false when creating the sysimage, the problem goes away.
Could it be that this is related to symbols being imported into Main and then causing circular references? Anyway, if someone else sees this, might be worth suggesting using that flag.
