We have just migrated hundreds of lists from Mailman 2 to Mailman 3. It was smooth in most of the cases. However, we just notice that there are some abnormal behaviour of Postorius for particular users who are owner/member of a large number of lists. We further look into a particular user who is owner of 84 lists. When the user login Postorius, only 50 lists are displayed no matter what the number of "Results per page" is chosen. Prev/Next page cannot be clicked as there is only 1 page. When I use the following mailman client snippet, it also displays the same 50 lists:
lists = client.find_lists('xxx@yyy.com', 'owner') for m_list in lists: print(m_list.fqdn_listname)
Did we hit any limit of find_lists? Is it a bug or are something wrong during the migration?
When the user use "Mailman settings", the page can still display all lists though (it's slow as it probably did a lot of SQL queries!).
