We've seen similar reports of (always) smbd getting stuck with our own 4.1.16 kernel: <https://forge.univention.org/bugzilla/show_bug.cgi?id=40558>
The common patch from my research so far looks like "unix: properly account for FDs passed over unix sockets", which might have introduced some suitable locking problem. It has been back-ported from 4.4 to several kernels by now. I'm not able to reproduce the bug with samba3.raw.composite in my 8 vCPU KVM environment. Some time ago I had a similar bug which I could only trigger on real-HW with 8 CPU. ** Bug watch added: forge.univention.org/bugzilla/ #40558 https://forge.univention.org/bugzilla/show_bug.cgi?id=40558 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1543980 Title: Kernel 3.13.0-77 crashes (can be triggered by Samba) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1543980/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
