High CPU usage and memory leak

[rty813]

When I use the pynng module, there will be occasional memory leaks, the available memory will gradually decrease, and the CPU usage will reach more than 120%. Since my program is more complicated, I'm not sure if it's a problem with the pynng module, or something else. So I want to ask, is there any way to troubleshoot?

There are some logcat screenshot.

1. lsof
   

2. strace (9742 is the problematic process)
   

3. top -c
   

4. mem_avail

Hi @rty813, I think I'm stumbling exactly in the same problem. The fact is that the leak happens very slowly, i.e. I see a very slow drift in memory usage. However, I'm also not sure if it's pynng or some other piece of code.

use nng, leak still happend. So, I think it's nng's problem.
