    Description

      This LSM cache stuck clean case does not look the same as WT-3694. The stress sanitizer job has 2 round of tests, one with the other without -enable-page-version-ts configured. The test failed at the round -enable-page-version-ts being configured. Also there's no page was dumped out in this case.
