LXCFS giving "unexpected cpu time:"

I am using lxc 2.0.9 and for correct view of /proc I am using lxcfs 3.0.0 on my custom hardware.
I am starting lxcfs in background and then starting lxc manually.

Out of 6 cpu cores, I have assign/shared four cores to my container via,
lxc.cgroup.cpuset.cpus = 2,3,4,5

My container is working fine , however I am seeing below logs on cosole.

bindings.c: 4917: proc_stat_read: cpu2 from /lxc/Container has unexpected cpu time: 29173 in /proc/stat, 31975 in cpuacct.usage_all; unable to determine idle time

Is this expected or something is wrong here ?
