[MM3-users] Problems with hyperkitty

Dear mailman support, We have an issue with hyperkitty. In the last month the space used by hyperkitty_email postgres table has increased from 54GB to 400GB and it is constantly increasing with no end. Is there any simple way of knowing what is taking so much space? Like for example display how much archiving space (or achived emails) is used by each mailing list? Looks like a mailing list has gone crazy but from the logs everything looks fine. Any help is very much appreciated. THanks a lot for your precious help!!
