Disconnection when using Windows 7 client

Please help us by providing the following info. Before posting please make sure that you're running the latest available version for your oC release: https://owncloud.org/changelog/ + https://owncloud.org/changelog/desktop/

Steps to reproduce
1. Turn on Windows 7 machine.
2. Start OwnCloud desktop client.
3. Wait to sync.

Expected behaviour

Files should sync.

Actual behaviour

After some time (I have thousand of files to check and sync), I get this messages:

Sorry, I attached the client log, obtained with "owncloud --logfile C:\xxxxxx\OCClient.log"
The owncloud,log does not have anything other than this (I don't see this as the nature of the issue...correct me if I'm wrong):

How many files do you have? Windows is currently a 32bit client. Please monitor RAM usage during sync.

There are a couple of bug reports related to this issue. Please update your owncloud to the latest release (https://owncloud.org/changelog/#latest9.1) and check if the issue has been solved. If not, please report to the bugtracker on https://github.com/owncloud/core/issues
