Ted Cabeen, thank you for your response. Would it be terribly inconvenient to test if a 12.04.03 client works with your 12.04.03 server? This would help narrow down if the issue is client, or server. Also, regarding your testing https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1243429/comments/15 was this tested on the client or server? ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1243429 Title: NFS Lockups with 13.04 clients to 12.04.03 server Status in “linux” package in Ubuntu: Incomplete Bug description: After a recent upgrade on my clients to Ubuntu 13.04 latest and Ubuntu 12.04.03 on the server, NFS4 clients began locking up with the errors below.

Hmmm. Hard to say. The server was at 12.04.02 when I took over management of the systems, and I upgraded the clients to 13.04 and the server to 12.04.03 at about the same time, so it's hard to disentangle which change caused the problem. I certainly had 12.04.02/12.04.02 client/server systems running properly. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1243429 Title: NFS Lockups with 13.04 clients to 12.04.03 server Status in “linux” package in Ubuntu: Confirmed Bug description: After a recent upgrade on my clients to Ubuntu 13.04 latest and Ubuntu 12.04.03 on the server, NFS4 clients began locking up with the errors below.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

[Kernel-packages] [Bug 1243429] Re: NFS Lockups with 13.04 clients to 12.04.03 server
** Package changed: nfs-utils (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1243429 Title: NFS Lockups with 13.04 clients to 12.04.03 server Status in “linux” package in Ubuntu: New Bug description: After a recent upgrade on my clients to Ubuntu 13.04 latest and Ubuntu 12.04.03 on the server, NFS4 clients began locking up with the errors below. Processes accessing NFS would hang up and lock, and could not be killed or adjusted. NFSv3 on the same server and client has been working fine. NFS4 was configured with clean defaults, no special options set. No log entries corresponding with the problem were seen on the nfs server.
