OSMC Freeze

Good morning everyone,

I’ve been having a problem for a few days with my Raspberry PI 3.
Here is my current setup: Raspberry pi 3, HDD with its own power supply, raspberry pi 3 connected in USB on my TV, and connected with an Ethernet cable.
I’ve been running on this setup for more than 2 years and I’ve never had any problems.
But for a few days I have big freeze problems with OSMC.
I started looking at my microSD card, and this one had a problem, so I made a new installation of OSMC 2018.1 on a new card.
But I still have big problems, it freezes in a totally random way, without any particular reasons.

Here are my logs:

Thanks in advance.
