Comment 3 for bug 855419

Hello nimu and David and everyone else affected.

Ubuntu One syncdaemon uses DBus system to make sure that there's only one instance running. In case there are more than 1 user dbus process running then it is possible that there are more than 1 ubuntuone-syncdaemon process. They will fight for the resources such as the metadata and each will rescan the local files making the system really slow.

So, if you are currently experiencing this issue please check the following:
1. All ubuntuone-syncdaemon processes are running as the same user:
ps axu | awk '/[u]buntuone-syncdaemon/ { print $2 " " $1 }'

2. There is only one user dbus process running:
ps xuw | grep [d]bus-daemon

if all syncdaemons are running as the same user and there's only 1 dbus daemon instance for the current user please open a new bug, collect the logs using:
wget http://people.canonical.com/~roman.yepishev/us/ubuntuone-ubuntu-syncdaemon-diag.sh
bash ubuntuone-ubuntu-syncdaemon-diag.sh

And attach the generated file (the name of the file will be printed by the script) to that bug report and mark it as private. Then please specify this bug report number in new bug report description to keep track of these.
