[Bug 84226] Re: Fast user switch applet causes high processor load
I'm seeing something similar on Gutsy (AMD64) with only 4 local users.
CPU usage goes to 100% as soon as I select another user from the list.
strace shows the following when I try the user switch:
sendto(19, FLEXI_XSERVER_USER ozlem\n, 25, MSG_NOSIGNAL, NULL, 0) = 25
ioctl(3, FIONREAD, [0]) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8,
events=POLLIN|POLLPRI}, {fd=10, events=POLLIN|POLLPRI}, {fd=11,
events=POLLIN|POLLPRI}, {fd=12, events=POLLIN|POLLPRI}, {fd=14,
events=POLLIN|POLLPRI}, {fd=13, events=POLLIN|POLLPRI}, {fd=16,
events=POLLIN|POLLPRI}, {fd=15, events=POLLIN|POLLPRI}, {fd=18, events=POLLIN},
{fd=17, events=POLLIN|POLLPRI}], 12, 0) = 0
read(19, 0x7fff4f646c9f, 1) = -1 EAGAIN (Resource temporarily
unavailable)
Is the \n supposed to be there with the user name in the call to
FLEXI_XSERVER_USER?

Can also confirm similar behavior on a NIS-based system with 6000+ users. fast-user-switch applet takes up all CPU, and locks up the gnome panel. -- Fast user switch applet causes high processor load https://bugs.launchpad.net/bugs/84226 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

We can confirm this bug having about 2500 users.

[Bug 84226] Re: Fast user switch applet causes high processor load
This happens at my installation too (getent gives ~10k registered users). When logging with a local user and the network disabled all is ok, but if the network is enabled the panel freezes on login and the fast-user-switch-applet task runs at 100%. Now, I can't remove the package as ubuntu-desktop depends on it, and while I've removed the applet from the default environment, there is no easy way to remove it from users desktops automatically on login... -- Fast user switch applet causes high processor load https://bugs.launchpad.net/bugs/84226 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 84226] Re: Fast user switch applet causes high processor load
Christoph: That's an interesting question because getent passwd loads every user on my Win 2k3 domain. This machine is authenticated to the domain controller via Samba ADS. # getent passwd ... real0m2.246s user0m0.016s sys 0m0.012s #time getent passwd |wc -l 3964 Thats a lot of users! Is there a way to limit fast-user-switch to local users only? Certain proprietary applications require me to be authenticated to the domain or I wouldn't need Samba ADS at all. -- Fast user switch applet causes high processor load https://bugs.launchpad.net/bugs/84226 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

This bug reapears on Ubuntu Gutsy (amd64). HW: Intel Core2Duo 2x2,0GHz, 2GB RAM, 500GB SATA-HD About 6 computers of the same system configuration. The Installation is Gutsy for amd64 with newest packages for now (02.Okt. @ 15:49). On login of a newly created user, the login hangs and top reports ~100% cpu-usage on one core. If f-u-s-a is removed from the panel all is ok.

Hm, maybe this high CPU usage is caused by the userdatabase? All systems are connected to a ldap, kerberos, AFS infrastructure with many user entries.
