[Nfd-dev] [EXT] ndnd memory increasing

[Junxiao Shi]

Hi Hao

This suggests a memory leak somewhere.
You can diagnose a memory leak with *pprof* tool.

See the following tutorial on how to use pprof:
Debug Golang Memory Leaks with Pprof - by Team CodeReliant
https://www.codereliant.io/p/memory-leaks-with-pprof

Once you find the bug, please open an issue on ndnd GitHub repository.

Yours, Junxiao
