I have a magento 2 site working however it keeps crashing randomly after running smoothly for 2 weeks. I reboot my site after the crash and it seems to stay for about a day or so before crashing again.
I've checked my system.logs and I have found this

I believe the issue is to do with my mysql server according to the log but I have no clue as to how to resolve this.
Any help would be much appreciated :)
