这个 Internal 区的内存很不正常，而且一直在涨，有什么办法定位到具体的代码吗

补充一下 detail ，大概就是这两个东西

[0x00007fbc19f03123] Unsafe_AllocateMemory+0xc3
[0x00007fbc05cb36e8]
(malloc=832MB #295)

[0x00007fbc19f03123] Unsafe_AllocateMemory+0xc3
[0x00007fbc04beaa94]
(malloc=343MB #100)

能知道里面的内容吗？

此贴已结，由于代码不是我这边维护的(我们只负责整体的技术架构)，在不熟悉它的代码并且代码量非常庞大的情况下没办法找到排查思路。所以直接限制了直接内存
