      Description

      FTDC can stall for a few reasons when the system is struggling, but this is just when it might be most helpful. Reasons include

      • out of tickets
      • cache is full and ftdc thread gets used to do evictions - the ignore_cache_size session option (WT-2932) might help here

      We should arrange for FTDC not to get stalled by these conditions.
