About 47 days after starting Konsole, Copy and Paste stop working. Selecting text by mouse or copying with ctrl+shift+c doesn't put the text into the copy buffer. Copying text in another program and trying to paste it into Konsole also doesn't work anymore. I suspect an overflowing 32 bit millisecond timestamp, although I have a 64 bit system. After restarting Konsole it works fine again for 47 days.
What a beautiful bugreport :) Windows 95 and 98 crashed after this uptime of the whole operating system. I never thought a desktop app could live for this long. Note: the 32-bit unsigned overflow of milliseconds is after 49.7 days, not 47. Could you by any chance check the behavior of some other apps after this long running time? I'm wondering, maybe KDE's (kwin's) Alt+F2 "run application" or something similar dialog box, or something from the desktop's right-click menu, assuming that it's part of a long-running process rather than a newly launched process there. I blindly suspect that this might be an issue in some lower level component (kdelibs, Qt or X11) rather than konsole itself. (Disclaimer: I'm not a konsole or kde developer.)
Note that I don't use KDE, but LDXE and Openbox. So I don't have many KDE apps running for a longer time. But I just checked KOrganizer and it seems to have the same problem. I restarted it and the problem was gone. Before that, KOrganizer probably has been running as long as the system is up, currently 151 days. For non-KDE-apps I didn't notice such problems. JEdit, Eclipse, Palemoon, Audacity and others are OK. So it may be a problem in KDE Frameworks 5.28 or Qt 5.7. Regarding the time I maybe miscalculated the interval. If I remember correctly, I restarted Konsole on October 4, and the problem occured on Nov 22. That's 49 days. It could just fit although it looks like it happened a few hours too early ;-)

This is a serious problem. I have VNC sessions that are never restarted unless security issues force a restart, and I used to be able to run them for months on end (one had an uptime of >300 days). This issue started happening recently (in last one year or may be since I moved to KF5 like 1.5 yrs ago), it wasn't the case earlier. How can we debug and make progress on it?
I can confirm the problem. konsole 17.08.3 copying died at day 49th :)
I just tested other long-running apps and it seems to be the same for krusader, kgpg and krunner (alt-f2) but in clementine it works... Also - in my case only copy stopped working (paste into these apps works w/o problems).

Thanks Kurt. If we can't work around this somehow, should we mark this as RESOLVED UPSTREAM?
Let's use needsinfo rather than resolved - let's see if/when it is resolved upstream. Feel free to reopen if there's somehow Konsole can work around.
This bug has had its resolution changed, but accidentally has been left in NEEDSINFO status. I am thus closing this bug and setting the status as RESOLVED to reflect the resolution change.
