when I login to GNOME, everything looks fine, but as soon as I open a nautilus file browser and close it again, and type ps aux in a terminal, I see: perry 28329 61.6 1.9 42932 20304 ? Rsl 14:37 7:10 nautilus --no-default-window --sm-client-id default3 CPU usage keeps on increasing(eventually reaches 99%), and I see TIME increasing as well. but when I open up a nautilus browser again, CPU usage slowly drops back to normal, and TIME pauses. and if I close it, the cycle continues. I did a little strace on nautilus and I found as soon as I close nautilus, it repeats the following cycle: ioctl(3, FIONREAD, [0]) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=10, events=POLLIN}, {fd=12, events=POLLIN|POLLPRI}, {fd=29, events=POLLIN, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=17, events=POLLIN}], 9, -1) = 3 ioctl(3, FIONREAD, [0]) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=10, events=POLLIN}, {fd=12, events=POLLIN|POLLPRI}, {fd=29, events=POLLIN, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=17, events=POLLIN}], 9, -1) = 3 ioctl(3, FIONREAD, [32]) = 0 read(3, "p\2\316\20H\325\f\0\0\24\4\0\20\0\0\0\0\0\0\24\24\24\24"..., 32) = 32 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=10, events=POLLIN}, {fd=12, events=POLLIN|POLLPRI}, {fd=29, events=POLLIN, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=17, events=POLLIN}], 9, 0) = 3 write(3, "\230\4\2\0\0\1 \1", 8) = 8 read(3, 0xbfffde20, 32) = -1 EAGAIN (Resource temporarily unavailable) select(4, [3], NULL, NULL, NULL) = 1 (in [3]) read(3, "\1\0\317\20\0\0\0\0\24\4\0\20\0\0\0\0\0\0\24\0\0\0\0\0"..., 32) = 32 ioctl(3, FIONREAD, [0]) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=10, events=POLLIN}, {fd=12, events=POLLIN|POLLPRI}, {fd=29, events=POLLIN, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=17, events=POLLIN}], 9, -1) = 3 ioctl(3, FIONREAD, [0]) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=10, events=POLLIN}, {fd=12, events=POLLIN|POLLPRI}, {fd=29, events=POLLIN, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=17, events=POLLIN}], 9, -1) = 3 ioctl(3, FIONREAD, [0]) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=10, events=POLLIN}, {fd=12, events=POLLIN|POLLPRI}, {fd=29, events=POLLIN, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=17, events=POLLIN}], 9, -1) = 3 ioctl(3, FIONREAD, [0]) = 0 poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=10, events=POLLIN}, {fd=12, events=POLLIN|POLLPRI}, {fd=29, events=POLLIN, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=29, events=0, revents=POLLNVAL}, {fd=17, events=POLLIN}], 9, -1) = 3 at first I thought this is caused by totem-thumbnailer, but same thing happens after I disabled all thumbnailing. and this is affecting only my user accounts, not my root account.

I forgot to mention, I'm using GNOME-2.10
I can't reproduce this behaviour. I'd like to ask you a few things: Can you try to find a consistent series of steps that reproduce the problem? Can you try to reproduce it on another machine? What version of nautilus specifically do you have? Could you attach a complete strace log? It's not clear what are the resources that are being constantly polled/read in your example (file descriptiors 3 and 4). Are you running the fam daemon? If so, what version? Are you performing a special action (downloading files, moving files around) when this happens? Do you have any other programs running when this happens?
Created attachment 60527 [details] nautilus strace I did the following to generate the strace log: 1.killall -9 nautilus 2.strace nautilus 3.close nautilus file browser window 4.open nautilus file browser window 5.kill strace nautilus
I'm using nautilus-2.10.0, the problem occured only recently, and I know it's not because of nautilus itself. indeet I'm running fam daemon, its version is 2.7.0-r3. and after stopping famd, I found the problem is gone. no, I was not running anything(other than the essentials for nautilus) when I discovered the problem.
and if you revert back to stable fam ?
I reverted back to fam-2.7.0, the problem persists.
maybe I made a little mistake before. this time even I stopped famd, the CPU usage still increases, so I guess this isn't really related to famd.
I just observed I can reproduce the same problem on gaim and gweather-applet-2. on gaim, I would start a conversation with someone, then close the conversation window, then I would see the CPU usage of gaim sky rocket. on gweather-applet-2, I would open its preference window, then close it, then gweather-applet-2's CPU usage would sky rocket. first I thought this happens to all GTK programs that opens up a child-window, but a few more tests showed this isn't true in all cases.
UPDATE: it seems the problem occurs on root account as well. but after switching off "always_use_browser" the problem stopped on nautilus, but persists on other programs.
I just found where the problem is, it was caused by scim-1.3.0. Since I have GTK_IM_MODULE=scim in my bash profile, it loads with every GTK program. Downgrade to scim-1.2.3 fixed the problem. I guess I'll file a seperate bug report on this.
