Thanks guys for providing some more details. Whats really needed is the mount arguments from the clients (the machines that have mounted the shared exports and are locking up) and the software versions from the NFS servers (the machines that are exporting files via NFS).
Specifically on the server it would help to see this on the servers: apt-cache policy nfs-kernel-server uname -a ifconfig -a Anything that will help build a solid repeatable test case. -- System lock-up when receiving large files (big data amount) from NFS server https://bugs.launchpad.net/bugs/661294 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
