Ok, aparently "download" was mounting from "osgeo6" via NFS and, at the same
time, exporting not only via HTTP but via FTP and Rsync as well.

After removing "rpcbind" both on "download" and "osgeo6", the NFS mount
stalled and all dependent processes were stuck.
It looks like the NFS mount was set up on Okt 19, 2017.  I hope I didn't do
this myself ....  At least this explains why "rpcbind" was installed on
exactly these two machines, which actually made me feel surprised when I
noticed its existence.

Cheers,
	Martin.
