Adding on to this to say we're experiencing this issue on all Ubuntu 18.04 systems and we're also running xfs for a filesystem. It seems to be related to /var/lib/lxcfs on all of those systems. When we exclude /var/lib/lxcfs from du, it completes without core dumping.

After the repair command, I mounted /var and ran du again with no errors. However once I rebooted into the full O/S, du aborted again in /var and /var/lib. The du and sudo du both abort, but non-privileged du also dumps core.
