Gigaspaces LRMI Java堆空间OutOfMemoryError

Question

我在轻远程方法调用协议（和看门狗）上收到java.lang.OutOfMemoryError：Java堆空间。 您可以在下面查看日志。 有谁知道为什么会这样以及如何解决呢？

我尝试更改代理，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  

这也没有帮助。 不过这很有道理-堆由于lrmi相关问题而失败，但是我看不到可以帮助解决该问题的设置。

我有一个8服务器配置，其中包含4个GSM，4个LUS，16个GSC（或8个GSC），8个主分区和8个备份（或仅8个主分区）。 当我尝试一一插入/写入对象时出现错误。 当我达到200000左右时（第一个达到该数字的分区失败，但以上情况除外。我可以看到RAM尚未进入字段-那里仍然有空间（8GB-已使用3.5GB-大约有4GB可用空间）。

我还在GSC控制台（在日志中找不到）中看到了一些其他有关FastConcurrentSkipListMap的迭代器的信息，该信息引起了该问题：

问题是gsc-s上的jvm从未变大，因为我对.bat使用了“ export”（linux）命令，而不是对环境变量使用了“ set”（windows）命令。 一旦增大了jvm堆空间，该问题就会消失。
