Hi folks, dmesg -T shows me a large list of messages : [Wed Aug 29 11:13:02 2018] NFS: nfs4_reclaim_open_state: Lock reclaim failed! [Wed Aug 29 11:13:02 2018] NFS: nfs4_reclaim_open_state: Lock reclaim failed! [Wed Aug 29 11:13:02 2018] NFS: nfs4_reclaim_open_state: Lock reclaim failed! [Wed Aug 29 11:13:03 2018] NFS: nfs4_reclaim_open_state: Lock reclaim failed! [Wed Aug 29 11:13:03 2018] NFS: nfs4_reclaim_open_state: Lock reclaim failed! [Wed Aug 29 11:13:04 2018] NFS: nfs4_reclaim_open_state: Lock reclaim failed! [Wed Aug 29 11:13:05 2018] NFS: nfs4_reclaim_open_state: Lock reclaim failed! : with a modification date appr 9 minutes in the future. NFS server and client have the correct time and are in sync, afaict. How comes? Kernel is 4.9.88-1+deb9u1 on the client, 4.16.5-1~bpo9+1 on the NFS server. Every helpful comment is highly appreciated. Harri
