Frederico, the best way to solve this is to provide a reproducible
example. If you file a bug report at the following with an example,
there'll be less of a chance that this gets lost:

Hi,
I have a DataFrame with 10 columns, say :c1 to :c10. I need to do a
groupby, grouping by 4 of these columns. When I try,
$ groupby(df,[:c1,:c3,:c4,:c7])
I get the following error:
MemoryError()
while loading In[13], in expression starting on line 1
in groupsort_indexer at
