Constant crashes since upgrading to 2017.7.4

Hi.

I upgraded to 2017.7.4 from 2017.6.x (the latest one) this morning and since then Home Assistant has restarted itself about 8 times.

Running supervised on a NUC. I saw there is a problem with the Ring integration but I don’t use that.

Every time it restarts all the logs are deleted. What can I do to find the problem?

Thanks
