Bug#820752: nfs-kernel-server: nfs server fails to start: nfds module can not be loaded: failed to allocate reply cache
No special VM settings. The system had an uptime of 17 days. The hardware is slightly odd, being a Zotac ZBox Nano CI320, which uses the Intel N2930, but it's stable and I have not had any other problems worth noting. I upgraded and rebooted to linux-image-4.4.0-1-amd64 and now the issue is gone. Not sure if it's because of the fresh reboot or the upgrade.

Do you have any VM settings in /etc/sysctl.conf or /etc/sysctl.d? Ben.
