Hey guys,
I’m currently on the hunt for a memory leak. So far, I was able to record memory allocations using Unreal Insights and confirming, that there really is memory leaking using the investigation tool. However, now I would like to know, where the memory is leaking, but in the Allocation table it does not show any callstack making it almost impossible to track down the origin. Yes, I sometimes get the LLM Tag as a hint, but that’s not really helpful.
So now I would like to know if there is a way to record the callstack. If it helps, I’m using Unreal 5.1 and starting the project from Visual Studio.
Hello! You need to also enable cpu tracing for the callstack to appear.
I have a similar issue but I do have CPU tracing enabled and still no callstack shows up.
You need to load symbols in memory insigths>modules before running investigation query.
You must select a specific time zoom in the upper timeline slider in order for callers and callees columns to show up. And caller/callees count for time spent within specific function calling hierarchies. The Incl(usive) col demonstrate total time spent within a method including all children method time cost, while Excl(usive) demonstrates total time spent w/0 considering any children method calls.
