Hi all, After considerable effort this week, we're down to one blocker for the 1.36.0-wmf.29[0] train: * MemcachedPeclBagOStuff: Serialization of 'Closure' is not allowed - https://phabricator.wikimedia.org/T273242 Thanks in advance for any help resolving this issue! Once resolved, the train can resume Monday (European) morning. -- Brennen, on behalf of your faithful train crew [0]. <https://phabricator.wikimedia.org/T271343>
