It appears that the goal of this case was to test balance and replace concurrency. But these two operations aren't meant to run concurrently and the replace failing errors are captured in the seqres.full output. Which are expected errors. To avoid further confusion, this patch adds comments. The reason to keep this test case is at the Link.
