Hello list, ...
Today, after an upgrade from lxc 2.0.0 to 2.0.3 + a full OS update, some
strange errors shed light.
In the terminal:
kernel:NMI watchdog: BUG: soft lockup - CPU#2 stuck for 22s!
.. beeps every 10 seconds or so.
top shows indeed rpc.nfsd with the given pid at continuous 100% CPU usage.
It renders the system completely out of control, even a reboot command
This behavior is getting started after starting a couple of containers.
On another server, the same upgrade took place, and after a couple of same
style errors (with kworker as I remember) - but the system started up and
so far runs as normal.
On a third system, there were no errors, but that had only one container.
My only hope now is that a distro update from fedora 23 to 24 will
eliminate the problem.
Might try an lxc downgrade before though ,...
Any suggestions appreciated.
Thank you, ...
