Problem MP set giveComport plugin runner thread current False new True spamming

i’m using some thread in my plugin, everything is working but i don’t understand why in the Mission Planner console, there are some spamming messages like this :

Stop making new threads for the same problem.

Firstly it’s not the same problem,
secondly since i don’t solve my problem i will continue.

I’m sorry i’m not here to embarass or to spam. I’m just here to solve my problems. I’m in an intership and i coded a plugin in c# (never use this before) and one month ago i didn’t know what was Mission Planner, Pixhawk or Mavlink. So i’m sorry if i’m not so accurate or i miss some important informations.
Thank you for helping me @geofrancis .
