    Description

      Link to example failing task.

      The generated JS test fails with a backtrace like the following:

      [js_test:rollback_test-8818-1618157223585-0] uncaught exception: Error: assert.soon failed, msg : Waiting for rollback to complete on ip-10-122-77-7.ec2.internal:20021 failed The hang analyzer is automatically called in assert.soon functions. If you are *expecting* assert.soon to possibly fail, call assert.soon with {runHangAnalyzer: false} as the fifth argument (you can fill unused arguments with `undefined`). :

      [js_test:rollback_test-8818-1618157223585-0] exiting with code -3
      

      Towards the end of the generated test, the rollback process is allowed to complete by making a call to {{RollbackTest.transitionToSteadyStateOperations()}}https://github.com/mongodb/mongo/blob/0782c59e71146e316e7d61ac61d76e2330f29eb4/jstests/replsets/libs/rollback_test.js#L321. This ends up failing due to an assert.soon() timing out.
