Dear list,

On a RedHat 7.3 NFS server with kernel 2.4.20-20.7smp, I'm currently
seeing the following effect after starting the nfs service:

The NFS service appears to start normally, exportfs is running correctly,
clients resume, reads and writes take place to the with usrquota enabled
ext3 filesystem. 3-10 seconds after that, this kernel message appears on
the console:

VFS: dqputduplicate(): Duplicated dquot put without duplicate reference

>From that moment on, the nfsd blocks. The load of the machine goes to 96
(the number of nfsds I set in /etc/sysconfig/nfs). Stopping the nfs
service now fails, it will leave one or two nfsd running in "D" state.

This is most probably no nfs problem, rather a problem of corrupted quota
information on the filesystem. I thought that I'd post this here anyway,
maybe there is a better way of handling this situation instead of having
to reset the machine?

Regards,
Marc
