| In Fink 1.9.0 and prior version, the managed memory fraction of taskmanager is controlled by `taskmanager.memory.fraction`, | ||
| and with 0.7 as the default value. This sometimes will cause OOMs due to the fact that the default value of | ||
| JVM parameter `NewRatio` is 2, which means the old generation occupied only 2/3 (0.66) of the heap memory. |
