Ok, so let's sit down and wait till it resolve on its own

BTW, I'm still using the antique but dashing bytes of version 0.7.7-2 and the bug is sometimes present in the morning. Good wifi reception all the night long and I see the CPU usage of Mitak server slowly increasing : 59.2 ... 59.3 ....

By closing and reopening the connections, everething is back to normal.
