      Description

      Sometimes the leaf page bytes statistic reports an unreasonably large value. Need to figure out why.

        Is this still open? Is there a repro?

        This is still an issue, to see the problem you can run wtperf like:

        $ WIREDTIGER_CONFIG="statistics=[all],statistics_log=(wait=10)" ./bench/wtperf/wtperf -O ../bench/wtperf/runners/medium-btree.wtperf
        $ grep "tracked bytes belong" WT_TEST/WiredTigerStat.*
        

        It will show a set of values that don't make sense. I've got a change in progress to fix the tracking.
