      Bug #28525 Node failures in PGMAN at ndbrequire (line 430) · babe38a4
      unknown authored
      storage/ndb/src/kernel/blocks/pgman.cpp:
        Under heavy insert PGMAN can run out of page entries
        even when set to 100 times page cache entries.
        
        In this use pattern the extra entries remain idle
        on LIRS stack.  Only ONSTACK is set.  There is not
        enough activity to free them the normal way.
        
        A study of PGMAN / DBTUP behaviour is needed.
        
        This patch adds new sublist SL_IDLE.  When page entry
        pool is empty, an idle entry is released from SL_IDLE
        front if there is any.  Otherwise, we still crash.
        
        The factor above is set from 100 to 10 (still high).
