Gigaspaces堆空间OutOfMemoryError

Question

我正在轻型远程方法调用协议(和看门狗)上得到一个轻型远程方法调用协议(和看门狗)：Java堆空间。你可以看到下面的日志。有没有人知道为什么会发生这种情况，以及如何解决？

我尝试的是更改代理、容器、查找服务和管理器的最大堆大小：

export GSA_JAVA_OPTIONS=-Xmx256m  
export GSC_JAVA_OPTIONS=-Xmx8192m  
export GSM_JAVA_OPTIONS=-Xmx4096m  
export LUS_JAVA_OPTIONS=-Xmx4096m  

这也没什么用。这是有意义的-堆正在失败，因为与lrmi相关的问题，但我没有看到一个设置可以帮助我解决它。

我有一个8服务器配置，4 GSM的4 LUS的16 GSC(或8 GSC的)，8个主分区和8个备份(或仅8个主要)。当我试图一个一个地插入/写入空间中的对象时，我会得到错误。当我到达大约200000时(达到这个数字的第一个分区，除上面的例外情况外，失败)。我可以看到，RAM还没有字段-仍然有空间在那里(8GB - 3.5GB使用-约4GB免费)。

我还在GSC控制台中看到了一些有关FastConcurrentSkipListMap导致问题的迭代器的附加信息(在日志中找不到)：

问题是，gsc-s上的jvm从来没有变得更大，因为我对.bat使用了"export“(linux)命令，而不是对环境变量使用"set”(windows)命令。一旦您使jvm堆空间更大，这个问题就会消失。
