I'm trying to upload a folder of about 1.5 GB to Ubuntu One. Everything seems to be set up correctly, and Ubuntu One says "File sync in Progress".
However, all it does is use about 3.3 GB of RAM (!) and 100% of one core, without sending anything on the network (as reported by system Monitor).
It's been like that for about 15 hours now (I left it on through the night).
What is going on here?
There is a bug for this here. Other bugs on this keep getting marked private so they are not visible. Please go to the bug and flag as "affects me to" If you need to attach log files so the Ubuntu One team can diagnose the problem, please open a separate bug.
There is known bug in Ubuntu One. On some systems (SSD harrdrives, from my experience) it tends to happen. Right now, I think best solution is to uninstall Ubuntu One, and replace it with something similar, like Dropbox.
