I have updated my 3 webservers to 16.07 but I am getting the following error message (attached).
I can only have 1 webserver updated and running at a time now which is odd because I have always had 3.
Every time I run this command: “sudo -u www-data php ./occ upgrade” it kicks one of the web servers out and acts like normal but one of the other one’s goes back to the update error message.
Does anyone know why this might be happening?
I have done this many times before and never had an issue with the upgrade.
Webservers (3 Servers)
