Did you remember to stop it first?

Very very similar to what I experience from time to time. (Posted about 
recently with zero response) Although my more drastic solution is to 
reboot the host, but I have gotten away with lxc-stop then a start.

I've now stopped using memory limits in containers and for the time being 
will let them swap (or share more memory with other containers and swap 
if needed) - they're mostly well behaved though.

I don't have a solution I'm afraid.
