LLM Profiling shows that EngineMisc is leaking memory overtime

This is the llv csv file,
LLM_Pid1520_2022.11.07-22.47.59_WindowsServer - 副本.csv (118.0 KB)
LLMPlatform_Pid1520_2022.11.07-22.47.59_WindowsServer - 副本.csv (36.3 KB)

Additionally, I’m using engine’s json modules and lz4 compressing modules, is this related?

UObject memory is fine, then what should I look for to locate the leak?
