Public bug reported:
Binary package hint: policykit-1
I'm observing periodic peaks in CPU usage of polkitd. This is a bit
annoying, as makes the fan of my laptop turn on every few seconds. I had
a look with strace and every time CPU goes up polkitd checks a number of
directories:
open("/var/lib/polkit-1/localauthority/10-vendor.d",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 9
open("/var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla",
O_RDONLY|O_LARGEFILE) = 10
open("/var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla",
O_RDONLY|O_LARGEFILE) = 9
open("/etc/polkit-1/localauthority/10-vendor.d",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 9
open("/var/lib/polkit-1/localauthority/20-org.d",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 9
open("/etc/polkit-1/localauthority/20-org.d",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 9
open("/var/lib/polkit-1/localauthority/30-site.d",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 9
open("/etc/polkit-1/localauthority/30-site.d",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 9
open("/var/lib/polkit-1/localauthority/50-local.d",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 9
open("/etc/polkit-1/localauthority/50-local.d",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 9
open("/var/lib/polkit-1/localauthority/90-mandatory.d",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 9
open("/etc/polkit-1/localauthority/90-mandatory.d",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 9
(These are only the "open" calls)
Now the problems seems to be that this doesn't happen once but 260 times
in a row (every time)!
This is on Maverick.
