      Description

      Noticed cache stuck on the following wtperf config:

      conn_config="cache_size=2GB,checkpoint=(wait=60)"
      table_config="type=file,leaf_page_max=32k,leaf_value_max=128k,split_pct=90"
      # The values are starting small, insert a lot so our database grows larger than
      # cache quickly.
      icount=20000000
      report_interval=5
      run_time=3000
      populate_threads=1
      # Continue inserting new records.
      threads=((count=1,inserts=1,throttle=1000),(count=4,update=1,update_delta=100))
      # Start with small values and let them grow slowly to large values.
      value_sz=20
      value_sz_max=65536

          Message: WT-3028 Don't check for blocked eviction with in-memory workloads. (#3159)

          • Don't check for blocked eviction with in-memory workloads. The cache can become full of clean pages so eviction can't make progress, but application threads are not blocked. We shouldn't fail in this case.
