g-s-d turning bersek (num-lock)
Last modified: 2012-08-25 14:23:16 UTC
Every once in a while, my system seems to freeze under hi-load. The visible effects are the num-lock led on the keyboard blinking like crazy, and the cpu heating up (fan increasing to full speed), and very quickly, the keyboard stops responding. Top shows a load of 20~30, with g-s-d, X and dconf all fighting for the cpu. When I attach gdb to g-s-d, here is what I get: (gdb) bt
+ Trace 230735
(too bad i didn't have the libkeyboard.so symbols, i'll need to rebuild g-s-d for that) dconf shows lots of activity on that numlock-state key: $ annotate-output +%T.%N dconf watch / 14:47:44.298552316 I: Started dconf watch / 14:47:44.499351228 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:44.501875502 O: 'off' 14:47:44.514671989 O: 14:47:44.575674379 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:44.577350656 O: 'on' 14:47:44.579003756 O: 14:47:44.644448394 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:44.646345153 O: 'off' 14:47:44.648166920 O: 14:47:45.102698377 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:45.105108528 O: 'on' 14:47:45.107678028 O: 14:47:45.181590467 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:45.184297519 O: 'off' 14:47:45.186597167 O: 14:47:45.259376082 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:45.261603797 O: 'on' 14:47:45.263719499 O: 14:47:45.338562123 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:45.340690483 O: 'off' 14:47:45.346952463 O: 14:47:45.416666781 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:45.418807495 O: 'off' 14:47:45.421000283 O: 14:47:45.494961263 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:45.500049944 O: 'on' 14:47:45.505452636 O: 14:47:45.587924014 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:45.589874832 O: 'off' 14:47:45.591743010 O: 14:47:45.675769441 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:45.677523835 O: 'off' 14:47:45.679180620 O: 14:47:45.741536980 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:45.743225441 O: 'off' 14:47:45.744847544 O: 14:47:45.820911272 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:45.823193567 O: 'off' 14:47:45.824960494 O: 14:47:45.931937809 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:45.933639774 O: 'on' 14:47:45.935281905 O: 14:47:46.004448489 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:46.010164259 O: 'off' 14:47:46.012260208 O: 14:47:46.067148304 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:46.068846464 O: 'off' 14:47:46.074514514 O: 14:47:46.134340067 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:46.139256230 O: 'on' 14:47:46.140983421 O: 14:47:46.213442400 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state 14:47:46.215293680 O: 'on' 14:47:46.216932935 O: 14:47:46.296642057 O: /org/gnome/settings-daemon/peripherals/keyboard/numlock-state ... If i kill g-s-d, or restart the session, everything goes back to normal. This is with g-s-d 3.5.90 & dconf 0.13.90. It started to happen a few weeks ago (somewhere in the 3.5.* cycle), sometimes 2 or 3 times a day, sometimes not at all in a week. I'm not really sure what's triggering this, i just seem to remember a few occurrences when starting my browser with many tabs in it. Of course, i'm not touching the num-lock when this happens, i always have it on.
