      Description

      If mongod is run on a machine with a very small amount of memory, for example <1 GB, it still configures a default 1 GB cache. This will almost certainly result in eventual failure of mongod when cache usage approaches the configured maximum and memory is exhausted. We could improve the user experience by either

      • fail early - refuse to start up in such a configuration
      • configure WT with a smaller cache by default
