You can disable metrics in the config

Ok i'll try what you said, please give me few days to test :D

If i turn off metrics, is it do anything bad to my server? ~~"

No. They're just for plugin developers to learn more about how servers use their plugins. If it's causing an issue it's safe to disable

I think the error is gone, thank you very much :D
