      Eviction Server currently uses a hazard pointer to remember its scanning position. It has a number of negative implications:

      1. The page it pinned in memory and can't be evicted or split.
      2. If the pointer is cleared, the eviction walk can't continue.
      3. We run into a trouble if there are > 1000 dhandles.

      Investigate the use of "soft" pointers like a key in a page or a "normalized position" of the page and implement it.
