nfs-kernel-server and 2.6.32-25-server

[Tobias Göller]

Hi kristau,

Sorry if I'm just hijacking your conversation with Patrick Hornecker (http://www.linux-archive.org/ubuntu-user/440140-nfs-export-problems.html) but I have absolutely the same issue after upgrading from a previous version of 2.6.32 kernel.

The nfs-kernel-server is going down with the following error:
Nov  2 22:30:52 cicero kernel: [ 4139.690018] rpc-srv/tcp: nfsd: sent only 780176 when sending 1048708 bytes - shutting down socket

After this only a restart of the server helps.

I have, indeed, high traffic running over NFS (~60 kvm nodes having their disk images stored on the nfs server).

Since the problem arised about 25 minutes after the kernel upgrade I am pretty sure something isn't right here.

I have booted the previous kernel where this issue isn't appearing.

Thanks!

Tobias
