New subject: Problems with Special:ActiveUsers since update from 1.22 to 1.24

28 Jan 2015

Hi,

since the update of MediaWiki from 1.22 to 1.24, which happened about 10 days
ago [1], ArchWiki has some problems with the Special:ActiveUsers page [2]:

* The number of users in the list is much lower than it should be according to
  the Special:Statistics page.
* The users in the ActiveUsers list are not the most recently active users
  according to Special:RecentChanges (but it happened several times that the
  list contained only my account, which could be related to that I was the most
  recently logged-in user viewing a page at that time).
* The ActiveUsers list will grow larger (but not large enough) when the page is
  reloaded frequently, but will be emptied after some time regardless of
  $wgActiveUserDays which is 30, the issue is only a few days old on our wiki.
* The second line on the ActiveUsers page says:
  "You are viewing a cached version of this page, which can be up to 29 days, 23
  hours and 40 minutes old."
  This value is too large, isn't it? Is it even configurable? I have been unable
  to find anything related. Also, I don't think the page was cached until 1.23
  or 1.24, so perhaps this is part of the problem...

As far as we know, ArchWiki is not the only one affected, see e.g. [3].

Thanks for any clues about the issue.
