You could use VMMap to look at the adress layout of a 32bit java process on your system.But as all the major java distributions are dropping support for 32bit you will have to move to the x64 runtime sooner or later, anyway. There you will not have this kind of problems.中文(繁體)...
当IoTDB的内存使用量超过MAX_HEAP_SIZE时,可能会导致性能下降、系统崩溃或其他不可预测的行为。以下是一些解决此问题的建议: 1.调整MAX_HEAP_SIZE 查看当前设置: 使用命令jps找到IoTDB的Java进程ID。 使用jinfo <pid> HeapSize和jinfo <pid> MaxHeapSize查看当前堆大小和最大堆大小。
1、堆(Heap)和非堆(Non-heap)内存 按照官方的说法:“Java虚拟机具有一个堆,堆是运行时数据区域,所有类实例和数组的内存均从此处分配。堆是在Java虚拟机启动时创建的。”,“在JVM中堆之外的内存称为非堆内存(Non-heap memory)”。 可以看出JVM主要管理两种类型的内存:堆和非堆。简单来说堆就是Java代码可及的...

You can see that the JVM primarily manages two types of memory: heap and non-heap. Simply put, the heap is the Java code of memory, is left to developers to use, non-heap is the JVM left to use, Therefore...

I discovered that setting the Java option -XX:MaxDirectMemorySize is effective at limiting the game's seemingly limitless hunger for memory outside the Java heap. I don't know what heuristic it uses by default, but my processes were regu...
