I have the same bug with ArchLinux. Both the server (i686) and the client (x86_64) are running ArchLinux with kernel 2.6.38.5 - everything connected with gigabit ethernet. The problem started after I've created a LUKS partition on the server and started accessing it with NFS.
Writing a file into the container using NFS will result in a total freeze of the client after some megabytes. The Server has two NVIDIA NICs while the client has an e1000 NIC. Mount line: server:/backup /mnt/backup nfs4 bg,hard,intr,nolock,udp 0 0 It seems that these freezes only occur if (Average write speed on the Server) < (Average Disk-to-Network speed on the client). That is the case if LUKS is enabled on the target partition. (50mb/s write speed on the server vs 90 mb/s read speed on the client). I'm not 100% sure whether this has anything to do with LUKS itself or just with the reduced speed. In general the 8169 module had and has (?) some problems handling heavy traffic (many connections, high transfer rate). That's why I replaced mine with the e1000. But it's likely that we blame it on the wrong module since the 8169 is pretty mainstream and almost everybody has one in his/her setup. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/661294 Title: System lock-up when receiving large files over a Realtek NIC (big data amount) from NFS server -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
