Just a question that i wasn't able to find an answer too after a lot of searching. 经过大量搜索后，我也无法找到答案。

Can a single instance of a java software use more than 10GB of ram on a server that has more than 128GB of RAM installed and still run fine without any issues? 一个Java软件实例是否可以在安装了128GB以上RAM且仍能正常运行的服务器上使用10GB以上的ram？ Or are there any limits on memory usage of a single instance of process. 或单个进程实例的内存使用是否有任何限制。

The maximum heap size for the Java Virtual Machine will most likely be constrained by your OS. Java虚拟机的最大堆大小很可能会受到操作系统的限制。 Theoretically, if you have a 64-bit machine, you can allocate the JVM a heap size of 2^64. 从理论上讲，如果您拥有64位计算机，则可以为JVM分配2 ^ 64的堆大小。 Since you have 128GB of memory, this is most likely your upper limit. 由于您有128GB的内存，因此很可能是您的上限。 Although, without knowing what your OS is, other constraints may arise. 尽管在不知道您的操作系统是什么的情况下，可能还会出现其他限制。
