I seem to have the  Zentyal email Server Locked up after updating to the kernel linux-image-3.19.0-51.
Had to revert back to 3.19.0-49   and seems to work. I am not using the SAMBA features in my Mail Server..

The same issue with Zentyal 4.2.2 linux-image-3.19.0-49-generic and linux-image-3.19.0-51-generic, usually it happens within 1-2 days, today I changed grub to use linux-image-3.19.0-47-generic, hope it helps. Thanks for tip.
 I had another issue, not sure if also connected with this, it is described here:

I've also had that issue. Brand new Zentyal install.

See post here: https://forum.zentyal.org/index.php/topic,27428.0.html

Samba thread caused the issue.

Physical machine, i5 Intel processor , 4 cores, 8GB ram, three people in it, was moving a few fils from old server to this one. Total lock up and had to pull the power plug. Top showed a work load of over 128.0

Can provide syslog if required.

Ok guys,

htop and top never shown stuck processes while 5 cpu (over 32) where maxxed out to 100%!
Memory looked ok, not fulled.

Needed to cold reboot since wasn't able to reboot normally.  >:(

I've seen there's out the 3.13.0.79.85...SAFE 2 UPGRADE or should I downgrade?

OOOOK, new symptom:

FIREWALL (and possibly DHCP and DNS) not working properly.

Firewall (& dhcp?)
Got packet drop with WINDOW=5840 RES=0x00 SYN URGP=0 MARK=0x1 without being able to log the drop via webadmin, only via syslog.
The weird thing is that the POS system is inside a newtork object with a static IP assigned. The only solution was changing the IP address (incrementing by 1, don't thing the value is to be considered)!

Now I'm reconnecting the issue I had the past 3 weeks with the voip system...which could really be correlated (same behavior).

DNS

Not sure, unable to confirm, but it wasn't serving the militarized zone

Has this happened to anyone?

Thx

Hi

Is there any news about this issue? I resently updated my Zentyal and I have same problems. Today I found this topic and I downgraded my kernel to 3.19.0-43 I hope it helps. But has someone reported this bug? Can we watch it and look, when it is fixed?
I have also Proxmox where inside running Zentyal Samba server.

When You have it installed - You can try to load that older kernel. But I think its from Zentyal 4.1 and Zentyal 4.2 brings 3.19 kernels.

Hi,

dear friends, I am also going through the same situation with Zentyal 4.2 installed on an HP ML110 host, in this case there is no problem of the link with virtualized environment.

Just a CPU crash, leaving the slow service and even compromising all other Zentyal services, to the point of halting the OS and have to restart.

Informardo was that just reinstalling the Samba service fixes the problem, or has otherwise?

No - we using older kernel
Samba update doesn't fix it right now.

Problem starts after upgrading to 4.2 and we using some older kernel in 4.2 branch. I am testing right now with 3.19.0.43 kernel.
