Memory leak using pandas dataframe

by

Confirmed that there’s some kind of memory leak going on in the indexing infrastructure. It’s not caused by the above reference graph. Let’s move the discussion to GitHub (SO is for Q&A):

https://github.com/pydata/pandas/issues/2659

EDIT: this actually appears to not be a memory leak at all, but has to do with the OS memory allocation issues perhaps. Please have a look at the github issue for more information
