From 5.7.0 through 5.7.4, nfs-server would not start upon boot on one of my servers. With 5.7.7 this was resolved BUT now when I reboot one of the NFS clients or unmount and remount an NFS partition on the client, the NFS server will sometimes spontaneously reboot. I get these messages in /var/log/dmesg.0: (The old dmesg log I assume is relevant since it would be the active one before the last boot). [ 40.302192] systemd[1]: Mounting NFSD configuration filesystem... [ 40.688313] kernel: RPC: Registered tcp NFSv4.1 backchannel transport module. [ 69.899630] kernel: NFSD: Using UMH upcall client tracking operations. [ 69.899635] kernel: NFSD: starting 90-second grace period (net f00000a8) After the NFS server reboots I see these NFS related messages in dmesg: [ 53.810062] systemd[1]: Mounting NFSD configuration filesystem...
