High CPU load on RPI 4b #61

Closed tlc76 closed 4 years ago

tlc76 commented 4 years ago

I installed py-kms on a RPI 4b with 4GB of RAM and I noticed it takes 100% CPU (1 core out of 4).

The log file is empty (size zero).

Is there any way to solve this?

Thanks Cristian

I re-run "git clone" and updated the local repository to the latest version. Everything works fine now. py-kms is listed on the second to last row:

It would be nice to know on which commit you had running it before the re-cloning. If this is fixed for you, please consider to close this issue now.

Thank you.

Well, that not what I meant, but whatever. Please close this issue now, if you don't need further assistance with this.

tlc76 commented 4 years ago

Apologies, I actually attached the git log because I don't know which commit I had installed at that time. Unfortunately I have no backup since that period... This is why I attached the git log, maybe it gives you an idea.

Thanks for your help, Cristian
