Ok,

after one week from the update of one machine to kernel 3.19.0-79-generic I can tell that everything looks back to normal, no issues whatsoever or freeze.
Updated the other servers, will keep You up-to-date.

Ok. Let's asume 3.19.0-79 solves the problem.

Will "apt-get upgrade" update the kernel after we did a rollback...?  Were kernel updates freezed with the rollback we did...? How to force kernel update back to normal?

Cannot find anything...

Thanks.

Up untill now everything looks normal and fine.

@peptoniET: Does the interface tells U to update? It should.
I think anyway that  "apt-get upgrade" will just do fine

not sure where you got  3.19.0-79  kernel i though they where only up to 3.19.0-51
apt-get upgrade will not upgrade kernels.
You need apt-get dist-upgrade  to upgrade kernel.
If you edited /etc/default/grub as in my previous post .that will keep booting by default the kernel you set there.
If you purged the faulty kernel then yes if you dist-upgrade then it will boot with newer kernel that may be installed
If you hold down the shift key when booting you should get the grub boot screen and be able to choose different kernels

I have been on the    Linux 3.19.0-47-generic    since feb 25 2016 and definitely no problem.
My server would stop responding after 2 days.I use samba a lot but no openchange.

Hi,

I had also the same issue in the last days on a Zentyal VM in Proxmox VE. Now I downgraded to 3.19.0-43 and we'll see what happens.
I would also like to know if any of the zentyal guy has something to say about this issue.

Regards

Develoer edition's users are feeling a little bit left alone here...

This is no graphic/minor issue, this is a HUGE, kernel-level disaster...

You should be on a 3.19 kernel if you are on zentyal 4.2
If I where you I would stay on the Linux 3.19.0-47-generic kernel for a few months if you want stability
There is the option to go to a 4.2 kernel that is in wily ubuntu15.10
see
https://wiki.ubuntu.com/Kernel/LTSEnablementStack

hope that helps

Thx @hotsummer98 for opening my eyes on the version numbers...I've read 3.19.0.83.89 instead of 3.13.0.83.89. A big f. mistake! Stupid me.

Right now I'm on 3.19.0-51-generic (as my previous comments on this post) and YES, I've already scheduled a "happy easter downgrade" =D
I need stability.
Still I would like to hear from devels...

Thx again.
