Description Ajinkya Patil 2017-02-12 16:02:05 UTC

Description of problem:
KDE panel freezes when a mounted nfs-share becomes unavailable

Version-Release number of selected component (if applicable):


How reproducible:
easily reproducible in the customer environment but not in internal environment.
 

Steps to Reproduce:
1.Start a KDE session on a RHEL7.2 workstation
2.mount a remote filesystem with NFS (v4)
3.disconnect the remote machine from the network, now the remote filesystem is no longer available.
4.After a while the clock in the KDE panel will stoop ticking and any action with the mouse on the panel does not have any effect
5.After you experienced the freeze, connect the remote machine again to the network.  After a while (sometimes immediately, sometimes it takes up to 10 minutes) the panel works again as normal (clock ticks, mouse actions work)

Actual results:
kde-panel freezes

Expected results:
removing nfs share should not affect kde-panel

Additional info:
* The freeze/unfreeze correlates with entries in /var/log/messages:
- freeze: "Jan 24 13:24:53 socvm092 kernel: nfs: server socvm098 not responding, timed out"
- unfreeze: "Jan 24 13:28:53 socvm092 kernel: nfs: server socvm098 OK"

Workaround:-
Disable device notifier from the kde-panel.
