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. -- 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
