There are more similar looking failures starting Jan 23rd I think, most on 6.8 but also some on 7.6 and 7.x:

7.6: https://gradle-enterprise.elastic.co/s/2ja2ns4flvi2u/console-log?task=:x-pack:plugin:frozen-indices:test#L6109
7.x: https://gradle-enterprise.elastic.co/s/gswoogmr3pkuy/console-log?task=:x-pack:plugin:frozen-indices:test#L6325

We need to force flush to make the last commit safe; otherwise, we might 
fail to open FrozenEngine. Note that we force flush before closing a
shard.
