Bug Description

on current oneiric, u1-syncdaemon creates many gigabytes of binary files in /tmp.

Magicicadad shows it is in "doing local scan".

I have logs turned on but there's a huge amount of output; let me know which ones you want.

magicicada shows it stopping and restarting somewhere after 'checking capabilities'.

The problem in syncdaemon.log seems to be this:

Hi Martin, do you have a syncdaemon-exceptions.log as well in your ubuntuone log dir?

Actually, nevermind. It seems there are two separate issues here. Another user has reported the issue in your second comment, as bug #824143. I'm using that bug for that issue. The original issue with /tmp may be a duplicate of another bug about invalid UTF-8 filenames, but I am not sure why it would make files in /tmp for those.

I do have those log files, but they're all empty (and very recent).
They might be like this because it was restarting in a loop and
rotating the log file every time.

I've had to remove the package because just stopping it from
magicicada didn't stop it looping. But I can put it back if you want
me to test something.

I am seeing a similar behaviour on Natty, not sure if it's related.

I enabled syncing yesterday for a folder containing about 1.5 GB of files, and left it running overnight. Returned this morning to find my filesystem had been filled up (only 30 MB space remaining) with about 12 GB of files in /tmp (and most of my files had not been synced).

From reading related bugs I have figured out that this probably began because I had a file with an unreadable filename, which I have now renamed and hopefully this will solve the problem for me.

However the creation of massive amounts of temporary files is clearly not right...

If I can help by posting any of my log files, let me know.
