+## Default Allocation Constraints
+
+| open_max | generic minimum | reserved | http | internal | rpc | files |
+| :--- | :--- | :--- | :--- | :--- | :--- | :--- |
+| **$\ge$ 32768** | 12288 | 512 | 128 | 64 | 64 | 4096 |
+| **16384 to 32767** | 12288 | 512 | 128 | 64 | 64 | 2048 |
+| **8096 to 16383** | 6144 | 256 | 64 | 32 | 48 | 1024 |
+| **1024 to 8095** | 512 | 128 | 32 | 32 | 32 | 128 |
+| **< 1024** | 256 | 64 | 16 | 16 | 16 | 64 |
+
+The baseline descriptor limits for each socket category are auto-calculated at startup or when calling `adjust_alloc` using _ulimit open files_.
+
+Allocation to other categories result in `generic` receiving less than `generic minimum` an `internal_error` is thrown.
