The formula for maximum usable swap is maxswapchunks * swchunk * 1024 bytes
maxswapchunks =16384 (maximum Value)
swchunk =2048 (which is default)
Since maxswapchunk value is set to the max you can increase the swchunk value, the total configured swap can be increased.
The maximum can be increased to 65536. But your we recommend that will be too high, so you can tune it to 4096 or 6144 (multiples of 4096).
