New failure, now with some additional logging: https://gradle-enterprise.elastic.co/s/biqntwh6sjaew/tests/overview

Some info from the [last failure]([gradle-enterprise.elastic.co/s/biqntwh6sjaew/tests/overview](https://gradle-enterprise.elastic.co/s/biqntwh6sjaew/tests/overview)) that might help reduce score a bit: Cluster the suite was run on: ``` [2025-07-21T17:36:55,097][INFO ][o.e.t.InternalTestCluster][testSortMissingNumbers] Setup InternalTestCluster [SUITE-TEST_WORKER_VM=[435]-CLUSTER_SEED=[7000333836992015345]-HASH=[11F7FEEE5A7]-cluster] with seed [61262E890F0E6BF1] using [0]...

Another [more recent one](https://gradle-enterprise.elastic.co/s/x4lci3xanwzho/tests/task/:server:internalClusterTest/details/org.elasticsearch.search.sort.FieldSortIT/testSortMixedFieldTypes/1/output).

Revisiting, this is probably also related to the [phase failures issues in batched execution](https://github.com/elastic/elasticsearch/pull/136889). So we should try to get that in first and then see if the failures here...

After https://github.com/elastic/elasticsearch/pull/136889 has been merged I would like to unmute this test and see if it still fails occasionally, wdyt @benchaplin? Let me know on https://github.com/elastic/elasticsearch/pull/137724 if you think that...

I unmuted the test, leaving this open just to check back in a couple of days if we see the errors again.

Labeling as "low risk" since from looking at the test failure history, this only occasionally fails on the 7.17 branch in mixed cluster bwc tests and thus looks quite limited...
