- Does KSysGuard crash again if you repeat a similar situation ? Thanks I really didn't try...the load was really high and my machine was lagging (runaway swapping) in a rogue app. I was trying to sort by cpu usage so i could kill the procs...but the sys monitor crashed. In addition, i really wasn't paying attention to what i was doing prior to the crash, since i wasn't looking for it... The crash is in fact related to the Qt library, and it is related to some component which will be difficult to debug/fix if we don't have more information. Please reopen if you experience this crash again. Thanks Actually closing now, no new information provided. |
Application that crashed: ksysguard Version of the application: 4.3.00 (KDE 4.3.0) KDE Version: 4.3.00 (KDE 4.3.0) Qt Version: 4.5.2 Operating System: Linux 2.6.30.5-43.fc11.x86_64 x86_64 What I was doing when the application crashed: This was running the process view of the system monitor applet under a fairly heavy load. The app crashed when I was attempting to sort the process list (which was in tree view at the time) by CPU percentage.
