      Description

      While running Workgen benchmark evict-btree-lookaside.py with a higher number of reader/search threads, we hit an assert in __wt_readlock() with following message:

       

      WT_CURSOR.search: __wt_readlock, 274: ticket == l->u.s.current && l->u.s.readers_active > 0
      		 
      WT_CURSOR.search: __wt_abort, 28: aborting WiredTiger library
