First, regarding memory configuration, I realized that the memory limit per fragment instance wasn't being distributed fairly among query threads. I've updated the logic to divide `maxBytesPerFragmentInstance` by `queryThreadCount` to prevent potential over-allocation. I also adjusted the initialization sequence to ensure the thread count is loaded before dependent memory calculations run. Second, I fixed a bug in `DriverTask` where calculating deadlines with large timeouts could result in an integer overflow. This was causing some issues with infinite loops during schema fetches, so I added a check to cap the value at `Long.MAX_VALUE` if an overflow occurs.
