我从 WebSphere Application Server 的 SystemOut.log 文件中得到以下错误：
[5/11/12 8:13:46:291 GMT+08:00] 000063c0 WebApp E [Servlet Error]-[ICMResourceManager]: java.lang.OutOfMemoryError: unable to allocate 79683 bytes for native buffer

似乎是本机OOM问题。我这里有个问题，这里的“本机缓冲区”和“直接字节缓冲区”一样吗？我可以尝试通过重置属性XX:MaxDirectMemorySize来扩大“本机缓冲区”的大小吗？顺便说一句，它的默认值是什么？或者我可以设置这个属性-Dcom.ibm.nio.DirectByteBuffer.AggressiveMemoryManagement=true以使本机内存空间动态？
