It's because we're hitting a limit in memcached when trying to cache the sudoer list:

PHP Fatal error: Allowed memory size of 104857600 bytes exhausted (tried to allocate 71 bytes) in /srv/org/wikimedia/controller/wikis/slot1/includes/objectcache/MemcachedClient.php on line 970, referer: https://wikitech.wikimedia.org/wiki/Special:NovaProject

Now that page loads, albeit very slowly. We should have enough headroom to keep working for a while now.

(Is there really a use case for Memcached here? I. e., what would happen if there was no cache?)

It's not a memory issue, that page is just too damn big if 'tools' is selected in the filter. If I increase max_execution_time then it loads just fine

(Cf. also https://gerrit.wikimedia.org/r/#/c/339832/ for reducing the size of the page :-).)
