In fle2_contention_kill_parent.js, the test runs a crud command with a hang failpoint set, waits for a failure, then runs the crud command again and makes sure the command succeeds.

In BF-26385, the command that runs when the failpoint is set does not seem to finish completely. Since the command that runs after the failpoint is disabled uses the same resources as the command run before, and since both commands are in transactions, they interfere.

It is not fully clear whether this is the issue with this test, but without more logging or more reproductions, we won't know what the error is here.
