<br/>
崩溃描述：
1.低概率复现，多次进场景才出一次
2. 崩溃时没什么特别的行为，就纯跑场景
3. 没改动引擎源码
4.Nanite部分CVar有调整：
r.Nanite.MaxPixelsPerEdge=2
r.Nanite.Streaming.StreamingPoolSize=512
r.Nanite.Tessellation=1
5. 编辑器（WITH_EDITOR）情况下没复现过，都是打包版本出现（Dev, Test, Shipping 均有复现）
<br/>
崩溃部分代码：
void FStreamingManager::AddParentNewRequestsRecursive(const FResources& Resources, uint32 RuntimeResourceID, uint32 PageIndex, uint32 VirtualPageRangeStart, uint32 Priority)
{
checkSlow(Priority < MAX_uint32);
const uint32 NextPriority = Priority + 1u;
<br/>
const FPageStreamingState& PageStreamingState = Resources.PageStreamingStates[PageIndex];
for (uint32 i = 0; i < PageStreamingState.DependenciesNum; i++)
{
const uint32 DependencyPageIndex \= Resources.PageDependencies\[PageStreamingState.DependenciesStart \+ i];
if (!Resources.IsRootPage(DependencyPageIndex))
{
if (AddRequest(RuntimeResourceID, DependencyPageIndex, VirtualPageRangeStart \+ DependencyPageIndex, NextPriority))
{
AddParentNewRequestsRecursive(Resources, RuntimeResourceID, DependencyPageIndex, VirtualPageRangeStart, NextPriority);
}
}
}
}
<br/>
看dmp 文件，DependencyPageIndex 这个变量都比较大，3161566976，还有几次崩溃都是比较异常的值
<br/>
想问下Epic有没有碰到过类似的崩溃堆栈，以及我们这边该如何进一步定位这个问题。
