Guessing a little here, but it sounds like a FIFO problem. Big delete, insertion of newer data, a thin scattering of old data left behind. If so, the cleanest fix is a coalesce after the delete has committed. It keeps the index size down, allows the maximum amount of space to be reclaimed, reduces the risk of node split failure with associated TX waits and redo generation.
