Hi,
I've read the problematic (and bugs) with 18.0.73, but I have had some 'new' problem during updating.
I was on 18.0.71#2 and I have tried to upgrade to 18.0.73#2 and this is my log :

I have tried to restart server and I have no errors and everything seems to be working fine now, but I still need to investigate further.
