[Bug 1572608] Re: Samba 2:4.3.8+dfsg-0ubuntu0.14.04.2 Reversion: CPU Soft Lock
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" https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1572608/+attachment/4661413/+files/octanesmb.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1572608 Title: Samba 2:4.3.8+dfsg-0ubuntu0.14.04.2 Reversion: CPU Soft Lock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1572608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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?

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!
