      Hi Roger,

Gesendet: Montag, 15. Juli 2019 um 10:10 Uhr; Von: "Roger O."
I have a strange thing in KDE with CIFS as a client. If a share is not
unmounted, but the server shuts down, large parts of KDE hang for a
long time (e.g., the status bar at the bottom). I think it is trying
to monitor the directories that are mounted. And when the server goes
away, the monitoring hangs. Could your KDE issues be because the NFS
server is not reachable? Or at least access to the share hangs,
causing parts of KDE to hang as well? If is hanging because of an
error on the server or client is a different matter. But it could
explain the KDE part of your problem.
You can expect, I checked a lot (about 100h poor working time).
Yes in the past, the server was also an issue, but this was fixed
since about 2 month. Afterwords it works mainly, but still some
crazy issues. But since about update to 5.1 on Server and Clients
either the booting hangs on a crashed "akonadictl" or they boots
slowly. Since the last update the duration was dramatically 
increased (since update to new KDE/Plasma 5.16?!) like described
below. For me it looks like an issue from update of some configs.
Especially akonadi have issues since about 5 Years, to migrate
my 20 years old kmail folders. 

To evaluate, the server issue, I started the user on the server,
but the issue seams to be similar.

Ulf

Hi Together,
since some month I've a lot of trouble with my about 20 Years
old Home network, which was all running on Tumbleweed:
Server (NFS 4 Server which is sharing /home config via YaST):
 |- Client1 (/home mounted via & user via NIS)
 |- Client2 (/home mounted via & user via NIS)
...
 |- Client5 (/home mounted via & user via NIS)
Remark: Server and Client user are synced via NIS/YP configurated
via YaST at Server and Client (basic setup was before about 20
years - last installation due to a root FS crash before about 1
year based on the Tumbleweed installation ISO).
On the most Clients KDE Plasma Crashes many times after login
If they are starting - it takes about 10 up to 30 minutes!!!!
Afterwords the system hangs from time to time with normal
load and only the tracker extract info below. What can I do?
One client I installed the last ISO (from 8th July) but this
one don't mount /home well, so I need to unmount it and mount
again via:
umount -f /home ; systemctl start home.mount ; systemctl status home.mount
# cat /etc/fstab (extract)
192.168.2.1:/mnt/nfs4/home                 /home      nfs  defaults  0  0
# cat /etc/fstab (extract - also tested with nfs4)
192.168.2.1:/mnt/nfs4/home                 /home      nfs4  defaults  0  0
# journalctl -xa (extract)
