Update Media Daemon: eats cpu despite being disabled
« on: December 26, 2008, 11:22:28 am »
Hi,

I spot weird behaviour of update media daemon. In web-admin->Files & Media -> Media Files Sync I have unticked media update daemon, but after few rebots I still notice it taking cpu:

Anyone with more insight ? Is tick on web-admin not working ?

Can Media Update Daemon be run on daily basis (at night) ?

Thanks in advance,

regards,

Bulek.

Merry Christmas and happy New Year for everyone...
Thanks in advance,

regards,

Bulek.

I've also noticed this. I think the daemon is restarted at boot time, regardless of the setting.

Maybe a bug?

* hari thinks it is annoying that it only sleeps for 2 minutes...

This has nothing to do with development, please post in the appropriate sections of the forum.

tail the update media daemon log file, then check/uncheck the box. It definitely works, so you should see the logging activity obviously start and stop when you do this. Don't forget that if you manually run a sync this will start a new process that will appear in top until it has finished its scan...

A mod should move this thread into Users...

I have an observation on this topic. I added a USB disk with a windows file format NTFS. I also saw a high CPU usage even with the daemon disabled. it was looking on the driver every few minutes. After removing the drive and deleting the windows partition I added the disk again. got it back to work and formatted it in linux as described in the wiki. See tutorials.

I do not see the high usage of my CPU. I do not know exactly why this is and cannot do more testing since I needed the drive for my files. Maybe something to test if you see this happening on your system.

Sorry about coming back to this post but since today I have a strange behavior again on my USB disk. I am not sure when it starts but suddenly my CPU is completely used. It is impossible to play any media from then. If I remove the USB drive the CPU goes down to the normal value again. I do not see a process that is using a huge amount of CPU power in the performance tool on the KDE desktop.

more people that have seen this behavior before

Don't do things like that from the desktop.

Use a shell from a remote PC (eg download PuTTY) and run "top". I till immediately tell you which process is consuming CPU

Thanks for the suggestion. Tried it and I do not see anything consuming high amounts of CPU. But still didnĀ“t solve my issues of being unable to normally play any media. I have removed a disk from another USB disk I found and add it inside the pc. Since the issue stopped when I remove the USB drive I hope it is gone.
