desktopcouch-se is eating up my cpu

[Endomancer]

Yesterday I installed Lucid Beta 1 and it was all running beautifully, could even use desktop effects and still run things at full screen without the screen going blank black (couldn't with Karmic). So I was very impressed.

This morning however, I decided to run the update manager to see what updates there were and found 448 of them which took about 3.5hrs to download.

After the updates I rebooted the computer and watched the cpu graph in conky top out in a matter of seconds and the culprit I found is desktopcouch-se which has been taking up all available processor usage.
I had previously never encountered descktopcouch-se or even know of it's existence before this morning, so I'm hoping someone could explain to me what it is/does and hopefully explain how to stop it eating up all the available cpu


Thanx in advance

Me too, but after upgraded many packages today it's seen get more good when done see the desktopcouch service on top `top`

Since Lucid is still in beta, the proper forum to post your questions is Development & Programming, Lucid Lynx Testing, not here.

I will be asking the Mods to move this thread there. Look there for future responses.

I'm having the exact same problem with Natty:

Any ideas?

It's been happening since I upgraded to the latest kernel 2.26.38-9. I had to upgraded to the unreleased kernel 2.26.39 to fix this: http://ubuntuforums.org/showthread.php?t=1762949 . However I'm still having the same issue with desktopcouch-se.

It seems to be related to UbuntuOne: https://bugs.launchpad.net/ubuntu/+s...ch/+bug/774295

And by the looks of ~/.cache/desktop-couch/log/desktop-couch-replication.log, it might be it :

Did you upgrade or is this a fresh installation of Ubuntu?

[edvar]

It's a clean fresh install of Natty from early May/2011:

uname -a
Linux ed-linux 2.6.39-0-generic #5~20110427-Ubuntu SMP Wed Apr 27 17:41:08 UTC 2011 i686 i686 i386 GNU/Linux

cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=11.04
DISTRIB_CODENAME=natty
DISTRIB_DESCRIPTION="Ubuntu 11.04"

Does this happen when you boot with a freshly made USB stick of Ubuntu 11.04 running?

[edvar]

I don't have a USB stick with Ubuntu. This is a desktop and I used a CD to install Ubuntu.

[linuxinstalledfromhdd]

Because I was going to suggest that you try leaving a "persistent" usb ubuntu live in the unit overnight booted and running, and check the logs in the morning to see if you can replicate the issue.
