Can't execute commands in container from host


I am using LXC 2.0.9 to run Android in my Linux host on my custom hardware and it is working fine.

I am not able to execute command in container name space from host. (via lxc-execute command)
I am seeing few error msg in “container.log” file.
lxc_commands - ../../../git/src/lxc/commands.c:lxc_cmd_init:1158 - Address already in use - Failed to create command socket /opt/C1/command lxc_commands - ../../../git/src/lxc/commands.c:lxc_cmd_init:1160 - Container "C1" appears to be already running.

This exist even after resetting the hardware. How to resolve this ?
(or to reuse the socket with existing binary packages ? )

In config for network I have,

veth = veth = lxcbr0 = up = eth0 =

Pretty sure you want lxc-attach instead. lxc-execute is an equivalent to lxc-start but runs a single command in the foreground instead of spawning init.
