This test failed during tear down here:

elasticsearch/test/framework/src/main/java/org/elasticsearch/test/ESSingleNodeTestCase.java

Line 134 in 0247199

assertThat(searchService.getActiveContexts(), equalTo(0));

Not sure why but it feels this test is a victim of something else. Set risk to low.

Added a waiting check for all free_context actions to be consumed before validating active contexts in #110595. Closing this one.
