[lxc-devel] lxc-stop: umount issue?

[Harald Dunkel]

Hi folks,

If a LXC server ran for several weeks and if I try to stop a
container, then the server gets stuck for a few minutes (see
attachment).

Please note the

:
[8541088.226013] Task dump for CPU 31:
[8541088.226015] mount           R
:

This might be common for all incidents of this kind, but I
lost some logfiles, so I am not 100% sure.

Is this a known issue? Any recommendations for a workaround?


The host runs Debian Jessie with kernel 4.9.30-2~bpo8+1. LXC
is version 2.0.8.

Every helpful comment is highly appreciated.
Harri
