udisks-daemon constantly burning about 10% CPU

[Igor]

Binary package hint: udisks

Following processes constantly burn CPU: udisks-daemon, gvfs-gdu-volume-monitor, dbus-daemon, gdu-notification.
This stated since install of Ubuntu 10.4.

I have been runing top since boot, no disk in DVD unit. This is tipical result:

I have tried to see what udisks-daemon is doing.
Command "udisks --monitor"
returns constant stram of following lines:

Command "udisks --monitor-detail" streams following:

There is no disc or anything in DVD unit. If I open tray, it's the same. If I put DVD disc in, then processes in question go to 0.
I can try to investigate more, if someone directs me how.

This problem has been bugging me for a long time - excessive CPU usage with gvfs-gdu-volume, udisks-daemon and dbus-daemon

I found the solution in this thread:

http://ubuntuforums.org/showthread.php?p=9601314#post9601314

[Igor (ikriznar)]

Seems to help me as well. Thnx.
This is just sort of a workaround. Or pooling should e disabled by default or should be made in a way, that does not burn so much CPU.

[jan (jan-ubuntu-h-i-s)]

With 3 USB disks attached, base load went up to 6 on my system.
Thus, no batch queue would run.
The workaround works well, but this should not occur.

[jan (jan-ubuntu-h-i-s)]

For what it's worth:
The 3 USB disks reported turned out to be the 4 inputs of my USB card reader.
All of them took a long time to find out to be empty, upping system load to 6.
On the same USB bus, there is a hub with a WiFi network stick.

Bus 002 Device 005: ID 050d:945a Belkin Components
Bus 002 Device 004: ID 058f:6362 Alcor Micro Corp. Hi-Speed 21-in-1 Flash Card Reader/Writer (Internal/External)
Bus 002 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I am using Lucid LTS:

[jan (jan-ubuntu-h-i-s)]

Another problem that I have had for a long time were disconnects from my Wifi network.
After some time, Network manager would not reconnect anymore, and messages would fill up every seconds with the logging below.

  sudo kill -s SIGSTOP `pidof udisks-daemon`

fixed this behavior.

As I nedded to access an USB stick, I had issued a
  sudo kill -s SIGCONT `pidof udisks-daemon`
And alas, after some time my Wifi disconnected again, and the log file filled again with messsages.
So now, I disabled the deamon again.
  sudo kill -s SIGSTOP `pidof udisks-daemon`
