      Problem Description:

      Chunkcache testing (WT-11010) isn't active on develop because it requires tiered storage, which is currently disabled in format testing (WT-10822). When tiered testing is enabled, Chunkcache testing will follow, but there have been timeout issues running test/format tests with Chunkcache configuration (see patch link in the comments).

      FYI - I have run format testing with chunkcache enabled numerous times and only observed timeout issues.

      Acceptance criteria:

      -The ticket requires the following work -- 

      • Reproduce the test/format hangs locally. 
      • Investigate and fix the hangs.
      • (scope changed: See recent comment)

      How to run the testing locally - 

      • For a fresh run (reproduces 1/10 times):
      format_args="tiered_storage.storage_source=dir_store tiered_storage.flush_frequency=100 checkpoint.wait=15 runs.source=table runs.timer=10"
      ./t $format_args
      ./t -R $format_args (this should run chunkcache)
      

      * From the failure config (couldn't repro )

      ./t -c CONFIG
      ./t -R
