Simply running “du -hc” on a large directory tree causes du to be killed because of kernel paging request failure in the XFS code. I ran slabtop, and it showed tons of xfs_inode objects. The system was rather unhappy after that, so I wasn't able to capture much more information. Is this a known issue on Linux 5.2? I don't see it with kernel 5.0.20. Those are plain upstream kernels built for x86-64, with no unusual config options (that I know of).
