Spacelynk Cpu load high

[domotiqa]

Hello,
I have a very high cpu load on customer Spacelynk. The Spacelynk wasn't installed by me, but I think it is very strange ! I tried to do a Factory reset without difference ! Do you have Idea ? I also upgrade to 2.1.1 firmware without any difference !
There is no script.. If I put the backup on my test Spacelynk th load is 0,1%

What is fun, is that when rebooting, it start from 0.5 then it's growing in the 3 min to more than 1

CPU/IO: 1.52 0.96 0.54, Memory: 11%, KNX/TP: OK
