I guess after kill -9, they are listed as defunct?
I have only seen this in conjunction with NFS and another application. Then restarting the NFS locking service helped get rid of them. On some systems the lockd is started automatically, on RHEL/CentOS 4 there is a nfslock init.d script. There could be other methods on other systems.
So check NFS locking is working even if lockd is running.
Look for dmesg and messages in the syslog.
At the moment I don't think the df processes are harmful for your server. But keep an eye on this.
