            Bug ID: 355673
           Summary: konqueror hangs after running for a while or during
                    cpu spikes
           Product: konsole
           Version: 15.08.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: teunis.peters at gmail.com

Konqueror display hangs on some cpu spikes (and sometimes recovers) and
eventually if left running for a few days.  (and even then some display might
still work, just no cursor or display of text during entry)
It's ... eventually.. 100% reproducible.   Anywhere up to 2 weeks...
A restart and session is lost - previous session is restored.
Starting  a second konsole and reproducing the layout (eventually - sometimes I
run 10-12 tabs - almost everything I do is console based) - and the new
instance works for same period.

Power management isn't a factor - my desktop and laptop both do this.  Ditto
video driver - laptop is Intel and desktop is nVidia.   Both are 64-bit, and
both running current ubuntu - so konsole 15.08.0. Kernel either - they run
different kernels due to some issues with laptop wireless.
I'm suspecting the connection with display is disconnecting and it's not
recovering properly - but that's just an assumption.   Haven't explored in
depth over how display is handled.

Reproducible: Always

Steps to Reproduce:
1. CPU spikes (sometimes)
2. Let it run for a week or so (eventually)

Actual Results:  
text stops being output on entry.  Sometimes all text freezes.   Entry
sometimes stops too - but usually continues.   Resembles ctrl-s/ctrl-q except
does not (usually) recover.

Expected Results:  
Console continues operating, cursor continues working.   Note : system console
works fine and can't reproduce, seems strictly konsole related.
