Hang in test/format

    • Type: Icon: Task Task
    • Resolution: Done
    • WT1.6.4
    • Affects Version/s: None
    • Component/s: None
    • None

      This CONFIG file is now producing a hang (see http://mjc.homeunix.org:8180/job/wiredtiger-test-format-stress/2171/console).

      In particular, a checkpoint walk is getting stuck because it hits a page in the WT_REF_LOCKED state, but no thread is doing eviction.
