LXC backup fail

[juniper]

Hi,

tryng to backup (suspend) on local storage one of my container i noticed:

INFO: suspend vm
INFO: lxc-freeze: 121: freezer.c: do_freeze_thaw: 54 Failed to freeze 121
INFO: lxc-freeze: 121: tools/lxc_freeze.c: main: 89 Failed to freeze /var/lib/lxc:121
ERROR: Backup of VM 121 failed - command 'lxc-freeze -n 121' failed: exit code 1

if i backup stopped all works fine...(obviously)

After stopping and restarting container, backup in suspend mode works fine....
