We have several servers, all running Debian 8 (up-to-date) and configured exactly the same by ansible. These servers run on different hardware / vps.
However, there is a difference between them in how they react on a reboot command (in this example two servers, using the same vm type hosted by the same service provider).
When logging in at server 1 (via ssh) and reboot, the connection is broken and i am back in the local client terminal. That's okay.
$ sudo reboot
Connection to my.server1.com closed by remote host.
Connection to my.server1.com closed.
However, server 2 "hangs" after reboot
$ sudo reboot
<terminal freezes>
What can be a possible cause of this different behavior? What do i need to check / change?
