2016-07-04 Thread Stefan Metzmacher
The soft lock up triggered by Samba was a regression in the kernel.
See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1543980
So it's fixed because you installed a fixed kernel.

I was finally able to try 4.3.9.  It *seems* to have cleared up the
problem, but the system is lightly loaded right now.  If the problem was
somehow load-related, only time will tell if it is really fixed.  Still
no idea what actually caused it.

Hi,

I'm having this issue, but its happening for me on Samba 2:4.3.9+dfsg-
0ubuntu0.14.04.3. Its the same CPU SOFT LOCK. Its been happening for a
couple of weeks now. Only way to get the server back is to power it off
and back on.

Do we know what it causing the issue?

Hi

In my case, both servers are connected to a Windows domain... Maybe that is
the difference ??

Ok, the RAM issue is discarded. It just happened again some minutes ago
and the RAM memory log I had set in place didn't notice a problem there.

I have no idea how to replicate the issue or what is causing it. So far
I've only noticed the soft lockup messages linked to smbd from dmesg,
syslog or kern.log, which start a few hours before the halt.

2016-05-12 Thread Gavin Chappell
I'm seeing similar behaviour too - on a Ubuntu 14.04.4 box, completely
up to date. I just had it freeze, which marks the third or fourth time
I've either had to Magic-SysRq it, or pull the power, since the Badlock
date.

The box has "plenty" of RAM (it was recently upgraded from 8GB to 16GB
in fact, some time in March) but I don't believe this issue ever
happened with 8GB and Samba 4.1.6. It acts as a file server for a small
office of 12 people, which I think would count as lightly loaded in
terms of Samba installations?

All I have so far is a snippet from /var/log/kernel.log of the call
trace which I've attached. If there is more information that would be
useful next time this happens, let me know what you need and I'll get
it. Unfortunately there is (currently) no load monitoring on this box,
so I don't know whether we're getting a similar increase in iowait time
before the crash - although the box is logging soft lockup errors, from
a user perspective the box is working perfectly fine until it freezes
altogether and stops responding to pings or console activity.

** Attachment added: "Sample smb lockup error - there are many more of these 
before the box froze"

2016-05-11 Thread Ed Huyer
I'm pretty sure it's not a RAM thing.  The system I encountered the CPU
soft lockup on has 192GB of RAM, and Zabbix shows it as mostly being
free when the problem occurred.

As an aside, Victor, are you sure this is the same problem you're
having?  Looking at your error log, it appears to be something else?  In
the release notes for the Badlock fixes there were a few new options in
smb.conf that can affect authentication.

Yes, this only happened after some upgrade last week. But I suspect the
upgrade might've caused a memory leak that eats up the ram under some
conditions. I still have to pinpoint what is happening, but it's my
guess at the moment. Let me know if you find otherwise! I am very
concerned by this.

I dont think it, because that is the same VM (CPU,RAM,etc) that work

I suspect the problem was due to low RAM memory. I believe smbd was just
the first to suffer but not the culprit.

we have problems with this new version too... the system stop to work (with out 
memory) after a time and I cant get the user list from the domain, like in this 
bug report:

Note1: wbinfo -u not work but wbinfo -g work perfectly.
Note2: on my case, rejoin to domain not work, only making a downgrade to the 
previous version (2:4.1.6+dfsg-1ubuntu2) work again.
