From time to time kdevelop eats all my memory when I open a kdevelop project. After killing kdevelop I can start it again, open the project and everything works. It's not an architecture dependend problem as I have it with amd64 and x86 using kdevelop 3.5.3 and 3.5.4. I'm not so familiar with gdb yet. If you tell me what to do, I hope I can provide better information. top - 22:40:51 up 3:09, 8 users, load average: 0.62, 1.02, 0.93 Tasks: 142 total, 1 running, 140 sleeping, 1 stopped, 0 zombie Cpu(s): 11.6%us, 7.7%sy, 0.0%ni, 76.6%id, 3.6%wa, 0.2%hi, 0.3%si, 0.0%st Mem: 2057276k total, 2036124k used, 21152k free, 8480k buffers Swap: 2000052k total, 1386088k used, 613964k free, 85312k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 22665 daniel 20 0 4159m 1.5g 1800 T 0 75.9 0:22.66 kdevelop 22645 daniel 20 0 318m 88m 1624 S 0 4.4 0:08.05 gdb 15300 daniel 20 0 341m 44m 9864 S 1 2.2 0:29.39 opera 5478 root 20 0 164m 32m 2444 S 5 1.6 3:02.45 X (gdb) run Starting program: /usr/bin/kdevelop [Thread debugging using libthread_db enabled] [New Thread 0x7fcf4efbb700 (LWP 22665)] QLayout "unnamed" added to IndexView "unnamed", which already has a layout kdecore (KAction): WARNING: KAction::initPrivate(): trying to assign a shortcut (Alt+Ctrl+Shift+N) to an unnamed action.
