Bad address - failed to exec /usr/sbin/init.lxc

Continuing the discussion from Container fails with the sync.c:__sync_wait:57 - An error occurred in another process (expected sequence number 7):

Some times the below error also seen

I solved the issue by adding the following line in the config file
lxc.mount.entry = /usr/sbin/init.lxc usr/sbin/init.lxc none ro,bind 0 0

but then facing another issue like below
