with root permissions
** Description changed:
Binary package hint: ubuntuone-client
Running Karmic on x86-64.
+
+ At least one of the files was copied over to ~/Ubuntu One as root. When
+ syncdaemon tries to hash (prepping for a sync) this file it gets a
+ permission denied error and then continues in a viscous loop trying to
+ hash this same file over and over again (see log in comment #5).
+ Changing the file permissions on this file from root corrects the
+ problem.
After moving ~320mb of versioned software repositories to my Ubuntu One
share, I've noticed that the Ubuntu One client is constantly working.
Further inspection with top(1) shows the ubuntuone-syncdaemon running
at max CPU and continually allocating more memory. This continued until
my system slowed to a crawl and I was forced to SIGKILL ubuntuone-
syncdaemon ( it didn't respond to SIGTERM ).
When I restarted the ubuntuone-client, the ubuntuone-syncdaemon appeared
to get in to its previous state, running at 100% CPU and constantly
chewing up more memory.
