Can anyone update me on the status of this bug?


Comment 2 Arjan van de Ven 2002-02-22 16:32:09 UTC
Are you by chance using NFS to export a novell mounted directory ?

Comment 3 Tracy Pham 2002-02-22 18:50:15 UTC
No,  I am not using NFS to export a novell mounted directory.  But I do use NFS
export a Sun Solaris mounted directory.

Comment 4 Steve Dickson 2004-08-11 10:57:35 UTC
This seems to be fixed in later kernels
