Public bug reported: I have a nfs server with multiple clients connected. I often fail to write very large files (1G orso) through the clients. It is strange that the problem does not always appear. But every time I met the the problem, the /var/log/messages file has the output like this:

A similar bug was reported from the kernel's bugzilla (http://bugzilla.kernel.org/show_bug.cgi?id=6858). A kernel version >= 2.6.18 doesn't have this problem. But I found that ubuntu-server 6.10's newest kernel version is 2.6.17. So I have to upgrade to 7.04 with kernel version 2.6.20.
