ledmon: Slow growing memory leak

[allanlaal]

after 35 days up, ledmon takes too much RAM:

Private  +   Shared  =  RAM used	Program
3.6 GiB +  10.5 KiB =   3.6 GiB	ledmon

might be good to consider adding a quick https://valgrind.org/ test for each PR

after 35 days up, ledmon takes too much RAM:

Are you using a packaged version (provide what version), or building from source repository (provide what commit)?

Thanks

@allanlaal,
please provide more details as @tasleson requested. We need to know if it is a recent problem introduced with library.
Then, we can start investigation.

[allanlaal]

it was in ubuntu 23.04 before version 0.95-2
sadly couldn't find what that previous version was
I'll reopen when I encounter it again

Thanks for feedback!
The one option I'm considering here is to add valgrind to CI.
Unfortunately, we don't have yet ledmon tests in CI so it must wait.

Thanks,
Mariusz

up 44 days and ledmon 0.97-0ubuntu1 memflooded again:

  Private  +   Shared  =  RAM used	Program
  7.3 GiB +  29.5 KiB =   7.3 GiB	ledmon

ubuntu 24.04 LTS, ledmon is installed via apt

I have 600GB of ram, so it takes me a while to notice

Hi @allanlaal
Are you able to build the code and test it? first of all upstream as, that the newest version is 1.1.0, and then the fixes proposed by @tasleson in #273. If not let me know.
