Bug Description
Running NFS server on Ubuntu Server 7.10 x86 (Pentium-3, 1G RAM).
- linux-image-
- nfs-kernel-server (1:1.1.
- nfs-common (1:1.1.
NFS clients (ubuntu, gentoo, fedora core) mount home directories from the server.
Works fine for a while after reboot, but at some moment (30 minutes to several days after last reboot) client applications (firefox, thunderbird, openoffice, ...) would freeze at start and the following error message can be seen in the syslog:
Jan 11 14:08:33 jig kernel: [ 5527.793749] lockd: server tango not responding, still trying
Jan 11 14:08:34 jig kernel: [ 5529.029039] lockd: server tango not responding, still trying
Jan 11 14:08:45 jig kernel: [ 5540.246812] lockd: server tango not responding, still trying
The nfsd, rpc.statd, rpc.mountd processes keep running on server. No relevant errors can be found in server syslog.
Restarting the nfs-kernel-server (on server) and nfs-common (on both server and client) would not help - the problem persists.
Have also tried nfs-user-server instead of nfs-kernel-server - no luck.
The only way to make it work is to reboot the server.

Since I have downgraded kernel to 2.6.20 (a week ago), the error does not show up anymore.
It appears to be a bug in kernel, 'cause I used to find a similar issue reported for Fedora Core 7, running 2.6.22.
