known issue PHP OOMing while computing authorsPostedIn

[Colonel_mortis]

FastCGI sent in stderr: "PHP message: PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 10485760 bytes) in [...]/system/Node/Statistics.php on line 118" while reading response header from upstream, client: [], server: [], request: "GET /forum/17-[...]/?sortby=views&sortdirection=desc HTTP/2.0"

That's in authorsPostedIn. It looks like there's two places where that gets called - computing the content that the current user has posted in, and computing which postedIn indicator to show.

The query that gets run for this will load about 260k entries (there are a bunch of topics with a very large range of contributors). I'm surprised that's enough to OOM PHP with 128M memory, but it seems to be the case.

For computing content that the current user has posted in, you can do a way more efficient query by filtering by user.

For computing the postedIn indicator, you could just skip it entirely on installs where that feature isn't used, but also I think you could make it much more efficient by joining the members in the query to just end up with the group IDs (though that query is probably a bit non-trivial).

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.
