Description
The script maintenance/cleanupWebSessions.py does not work for millions of web sessions, because it first collects all sessions keys, and then removes them. The script exhausts memory on a machine with 4GB memory.
The solution is to simply find and remove sessions in batches of small sizes, like 1000.

Martin,
Thanks for the contribution, but I believe there is a better solution which involves using iterators.
I will add the fix, and take the opportunity to finally move this to a scheduler task.
Give it a try and let us know, please.
