I've tried all of the 10.10 ppa kernel backports as they are made available. This has made no difference. Each one in turn.
I've also played with the mount lines. Here are some of the combinations I've tried: rw,noatime,nfsvers=3,udp,rsize=32768,wsize=32768,actimeo=3,sloppy,addr=135.149.74.51 udp -> tcp no nfsvers=3 no actimeo no noatime The addr= bit was added because I had a NIC with multiple IP addrs and thought that that might be confusing it as the NFS docs state that the "server IP resolution logic" is not entirely correct. There are however some servers that have this problem and some that don't. OK: Intel(R) Xeon(R) CPU X5680 @ 3.33GHz Not OK: Intel(R) Xeon(R) CPU E5405 @ 2.00GHz AMD Opteron(tm) Processor 280 Intel(R) Xeon(TM) CPU 3.00GHz They are all using the same mount args as provided by LDAP autofs. It may be just the use case that has prevented it from happening on that one server. -- 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
