No this did not happen after an upgrade. I built 3 brand new ubuntu 14.04.4 LTS servers all pushing nightly backups to my NFS server. I have no problem with the other two servers as their data is not large. They still work fine. Its always the one with the large data that seems to choke. Which of course is my main mail server.
I'll try the new upstream kernel and let you know how it goes.

System integrity is still responsive. I'm running NFS version 4 on Ubuntu 14.04.4 LTS and during large rsync file copies (200MB+) they die midway. This is killing my zimbra email backups :(. I haven't had the system freeze during this scenario but what ends up happening is the copy fails on the client side and then my NFS server shuts the socket down due to excessive failures. Smaller file copies work perfectly fine. Here are the client/server logs. #Client Jul 9 01:00:39 mailserv01 kernel: [591473.216168] nfs: server NFS-Backup01 not responding, still trying Jul 9 01:00:39 mailserv01 kernel: [591473.216174] nfs: server NFS-Backup01 not responding, still trying Jul 9 01:00:39 mailserv01 kernel: [591473.218841] nfs: server NFS-Backup01 OK Jul 9 01:00:39 mailserv01 kernel: [591473.219159] nfs: server NFS-Backup01 OK Jul 9 01:01:14 mailserv01 kernel: [591508.710863] nfs: server NFS-Backup01 not responding, still trying Jul 9 01:08:16 mailserv01 kernel: [591929.870358] nfs: server NFS-Backup01 OK Jul 9 01:08:44 mailserv01 kernel: [591958.514953] nfs: server NFS-Backup01 not responding, still trying Jul 9 01:10:23 mailserv01 kernel: [592056.840273] nfs: server NFS-Backup01 OK Jul 9 01:11:19 mailserv01 kernel: [592113.298900] nfs: server NFS-Backup01 not responding, still trying Jul 9 01:13:07 mailserv01 kernel: [592221.275966] nfs: server NFS-Backup01 OK Jul 9 01:15:22 mailserv01 kernel: [592355.580401] nfs: server NFS-Backup01 not responding, still trying Jul 9 01:15:22 mailserv01 kernel: [592355.615649] nfs: server NFS-Backup01 OK Jul 9 01:16:03 mailserv01 kernel: [592397.459848] nfs: server NFS-Backup01 not responding, still trying Jul 9 01:16:08 mailserv01 kernel: [592401.663381] nfs: server NFS-Backup01 OK Jul 9 01:17:06 mailserv01 kernel: [592460.381059] nfs: server NFS-Backup01 not responding, still trying #NFS Server Jul 9 01:01:51 NFS-Backup01 kernel: [130980.762798] RPC request reserved 156 but used 176 Jul 9 01:08:28 NFS-Backup01 kernel: [131377.839675] RPC request reserved 156 but used 176 Jul 9 01:08:46 NFS-Backup01 kernel: [131395.943517] rpc-srv/tcp: nfsd: got error -32 when sending 136 bytes - shutting down socket Jul 9 01:10:17 NFS-Backup01 kernel: [131486.962508] RPC request reserved 156 but used 176 Jul 9 01:10:22 NFS-Backup01 kernel: [131492.447565] RPC request reserved 156 but used 176 Jul 9 01:10:27 NFS-Backup01 kernel: [131496.837561] rpc-srv/tcp: nfsd: got error -32 when sending 136 bytes - shutting down socket Jul 9 01:10:54 NFS-Backup01 kernel: [131524.423501] RPC request reserved 156 but used 176 Jul 9 01:15:31 NFS-Backup01 kernel: [131801.603553] rpc-srv/tcp: nfsd: got error -32 when sending 136 bytes - shutting down socket Jul 9 01:16:55 NFS-Backup01 kernel: [131885.232973] rpc-srv/tcp: nfsd: got error -32 when sending 136 bytes - shutting down socket #Client fstab NFS-Backup01:/mnt/backup /mnt/backup nfs rsize=8192,wsize=8192,nfsvers=4,hard,timeo=14,intr #NFS Server fstab /mnt/backup /mnt/backup none bind 0 0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1602827/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
