Hi, I am having Identical behavior with 8 machines (with a set of about 100 files), what's more is all the machines have crazy amounts of I/O happening, when they're on the LAN, its upwards of 10MBps, and I have remote clients that are clogging my 20/20 WAN. Are you seeing something similar. Also look at your log files on the linux host, mine is showing up with thousands of "WriteToDisk: Permission denied" Even though I've attempted to delete these multiple times, and have granted all permissions for the files and directories several levels up. I just cannot seem to get rid of these, and as a bonus, I just discovered the BTsync has been deleting perfectly good data and replacing it with empty directories. Any thoughts?
