Bug ID: 502858
Summary: Having digiKam open for extended periods of time
(12+hrs) the images will fail to load and thumbnails
turn to the generic (universal) "image" icon
Classification: Applications
Product: digikam
Version: 8.6.0
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Albums-MainView
Assignee: digikam-bugs-n...@kde.org
Reporter: ticedo...@hotmail.com
Target Milestone: ---
SUMMARY
After DK runs for some period of time (12hr or more), the previews for some
images show up like normal, but some are the generic icon for "image" in
windows.
Then, clicking on ANY of the thumbnails will produce an error message on the
main image screen: [Failed to load image].
I have digiKam running on my Windows 10/11 setup using a remote MySQL server
for the core, faces and similarities db, and all the images and video are on an
SMB share mounted as "P:"
If I restart DK, everything works fine for the next 12hr or so. Then it
repeats.
STEPS TO REPRODUCE
1. Let the PC run for a long time - 12hrs plus
2. Open an album, then click on a thumbnail image
OBSERVED RESULT
The main image viewer panel opens, but no image is displayed, and it is a blank
white screen
There is only a note in the upper right side of the main viewer: [Failed to
load image]
EXPECTED RESULT
Should open the larger image that is being previewed by the thumbnail and/or
all the thumbnails should show the image's small scale version of the image and
not the generic (universal) icon for "image".
SOFTWARE/OS VERSIONS
Windows: Win11 (24H2 OS Build 26100.3775) and Win10 (22H2 OS Build 19045.5753)
ADDITIONAL INFORMATION
The NAS is a WD PR4100 with two 1Gbps Eth using channel-bonding, and there have
been no alerts from the NAS or the switch to indicate a port issue.
All the PC have either 1Gbps or 5Gbps Eth ports.
The backend is MikroTik switches (mix of 1Gbps to 10Gbps)
The MariaDB is a docker image (11.7.2-MariaDB-ubu2404) running on Rocky 9.5 on
a Mac Mini (late 2014 i7 / 16GB / 1Gbps) with the core, faces and similarities
DBs setup and loaded with data.
NOTE:
It's acting like the network connection was lost on the PC or the NAS / MariaDB
server went offline.
I would expect if this was the case, rather than having to restart DK, it would
reconnect and carry on after such a network issue.
I could be wrong, but I don't think this is a network issue.
One of the PC using DK is hosting a qBitTorrent client that is using the same
NAS, but a different shared drive. The qBt client never gets an error message
about missing files (that would be normal for a flaky network connection or the
NAS going offline). However, it is not using the MariaDB server for anything
other than digiKam.
