Bug Description

Split from bug 1433432:

"1) for active server n_flushed is being added to, and reset only by idle server flush, resulting in wrong counter values (typo += instead of =)."

This in itself can cause CPU spin for the cleaner thread, but does not fully resolve the issue in bug 1433432.
