This is becoming a pretty serious issue for us.  We have more that 15 local servers (both hardware and VM's) many of which are development machines.  Which means they are often rebooted or otherwise taken off-line.

When that happens to a machine that someone has mounted an NFS share from, those with that mount get locked up.

Can someone from KDE please chime in on why this has to be so?

We don't use Gnome or any other DE, so I don't know if this is a KDE problem or a system problem.
