            Bug ID: 474403
           Summary: Freezing Issues with Network Mount
    Classification: Applications
           Product: dolphin
           Version: unspecified
          Platform: Archlinux
                OS: Linux
            Status: REPORTED

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.

STEPS TO REPRODUCE
1.  Setup a Network Mount (CIFS or NFS) in /etc/fstab.
Example: 10.1.10.102:/mnt/volume /mnt/volume nfs4 x-systemd.automount,
x-systemd-idle-timeout=20min,_netdev 0 0

2. Mount said network mount point.

3. Attempt to copy a large file (I used a 20GB file) to said moint point. It
may also happen with a large amount of small files but I did not attempt that.

OBSERVED RESULT

The copy dialog will appear and start to copy. It will hit a random percentage
and seems like it stops copying. The dialog window and the destination dolphin
with will then go grey if an attempt is made to interact with one of them. You
are unable to do anything until eventually the copy/move process is complete.
You are also unable to open a new dolphin window and browse the network mount
point until to copy is complete.

EXPECTED RESULT

I would expect I would be able to copy a file without dolphin hanging
up/freezing. I would also expect to still be able to browse the network share
without any issue except maybe a little slower since a copy is occurring and
using most of the network bandwidth is likely being used. So the browsing may
need to wait a few moments to intercept some bandwidth.

SOFTWARE/OS VERSIONS
Windows: N/A
macOS: N/A
Linux/KDE Plasma: 

Arch Linux

KDE Plasma Version: I believe it was 5.27.7 but I can confirm at a later time
(It would be the latest version that Arch Linux provides in their repos)
KDE Frameworks Version: Unsure but will confirm at a later time. (It would be
the latest version that Arch Linux provides in their repos)
Qt Version: Unsure but will confirm at a later time. (It would be the latest
version that Arch Linux provides in their repos)

ADDITIONAL INFORMATION

One interesting thing I came across while doing some testing was that if I
browse to the share using Dolphin's built-in faculties for Samba Shares (Going
to the Network Section/Pane, then typing in a Samba network address
smb://10.1.10.102). It works perfectly as expected. I am able to browse the
share, copy a large (20GB) file, and continue to browse the share without any
issues.
