I'm seeing an out-of-order return error, repeatably on pixiebob:
t, file:wt, WT_CURSOR.prev: WT_CURSOR.prev out-of-order returns: returned key 82575 then key 82575: Invalid argument
It's similar in a couple of ways to sue.loverso's report in WT-2575, it's a heavily-threaded, in-memory, variable-length column-store run. Here's the CONFIG:
