The 1.38.0-wmf.9 version of MediaWiki is blocked on group0[0] due to a memory leak.

The new version is deployed to group0[1], but can proceed no
further until these issues are resolved:

* T296098 - 1.38.0-wmf.9 seems to have introduced a memory leak

Once these issues are resolved train can resume.

Thank you for your help resolving these issues!

Hello,

It might have been related to T296063 - 4x increase in database queries after deploy of 1.38.0-wmf.9 to all wikis, though we are not entirely sure.  After discussions, I will roll 1.38.0-wmf.9 to all wikis now and we will monitor memory usage.
