      Description

      format failed to report a stuck cache

      format failed on kodkod (http://build.wiredtiger.com:8080/job/wiredtiger-test-format-stress/56873/consoleFull), with format run exceeded 15 minutes past the maximum time, aborting the process.. Looking at the core, it's clear the cache is stuck, but we did not get the usual cache dump in this case.

      Here's the CONFIG:
