Everything crash 2-3 time each day

Hi, since a week or two my setup crash 2 or 3 time a day. My habpanel load, but doesn’t answer and it’s does the same thing with the basic UI… Somme command happen like a minute later and some random command two ( may be rule that triggering late )

when this happen I log out and restart Openhab and it work fine again

I was in 2.0.0-SNAPSHOT Build #717 so I update to 2.0 release build to try if it would fix my issue but it still crash 2 or 3 time a day

Here my log file it’s a little messy but if you look the most recent log there is some errors…
