Bug ID: 399945
Summary: Panel & other desktop functionality hang following
network drop if CIFS mounted SMB directory exists
Product: plasmashell
Version: 5.12.6
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Panel
Assignee: plasma-b...@kde.org
Reporter: d...@aninstanceofme.com
Target Milestone: 1.0
If network connection is lost while a SMB share is mounted with CIFS, or the
SMB share becomes unavailable on the network for other reasons, the panel and
other desktop functionality hangs for several minutes.
During this time, attempting to open the menu opens only a blank,
semi-transparent pane, which sticks in the 'open' position. Clicking other
panel object or tray items - such as the 'network manager' icon, yields no
response. Dolphin becomes unresponsive.
In short, all desktop environment graphical elements are rendered almost
entirely dysfunctional. Konsole does still work to a point, however attempting
to enter or list the SMB directory hangs the session. In that case, another
terminal session (tab or window) needs to be opened to resume using Konsole.
After several minutes of this hang, normal service appears to be resumed.
STEPS TO REPRODUCE
1. Mount an SMB share with CIFS.
2. Disconnect from the network.
3. Attempt to open the main menu on the panel.
OBSERVED RESULT: As summarised above.
EXPECTED RESULT: Desktop functionality remains unaffected by network loss and
associated loss to access to the source of the CIFS mounted SMB share.
