          Description

          Several test/format jobs failed overnight with a stuck cache after the latest code changes. This one on zseries is reproducible elsewhere. I hit it on AWS within 10 iterations. This is changeset e189aa8a.
          http://build.wiredtiger.com:8080/job/wiredtiger-test-format-stress-zseries/10198/

            Issue Links

            is duplicated by

            Question - WT-2891 Test format can hang indefinitely when cache's dirty threshold is exceeded

            • Major - P3 - Major loss of function.

              I confirmed that the issue is with the new changes from WT-2902. Running changeset 09f65fffa737 just before that merge runs the 100 iterations to completion.

              Message: WT-2913 Re-sort eviction queues if we find no new candidates. (#3043)

              We could be in a situation with a tiny number of pages in cache, all of
              which are already queued. The queue needs to be re-sorted so that some
              of those entries can become candidates. This caused hangs in some
              test/format configs.
