Well, after auditing a little bit more with tcpdump I found out that the 
getattr() NFS calls from the client actually originate from konqueror in file 
mode. When I kill the process the getattr traffic apprently stops so maybe 
this was the cause for it.  However, since this is not 100% proven yet, the 
auditing isn't over..

Boris.
