lxcfs error

Hey!

I am having issues with lxcfs library. When I run 'df' the system will say:

/var/lib/lxcfs: Transport endpoint is not connected

When I run 'service lxcfs status', the output is:

lxcfs.service - FUSE filesystem for LXC

This is on a ubuntu server running a SFTP server. Everything is running fine, I was just wondering why there is this problem and how to sort it out.

Thanks in advance
