Can someone please explain to me why when a folder gets over 100GB BTSync seems to just stall out? Ive tried to set this up many ways and now I have a the secret setup on the remote computer as a read only folder I am looking at the sync queue and its telling me its "syncing 2,061 files" yet is just sits there. Secret setup on MAC OSX Read only folder located on Win Server 2008 R2 Please help before I abandon BTSync.
