I'm syncing data across about 14 computers, some of them being very large video files. At the moment, this is all on computers using Windows 7, on a Gigabit LAN. I find that on my master backup computer, every 30 minutes to an hour, the BT Sync app will freeze. When I view it in the Task Manager, under Processes, I see that it's using 00 CPU, but it consistently freezes with a memory usage of 850,000K - 900,000K. Is this a memory leak issue, perhaps? I was using a previous version of BT Sync (I'm sorry that I can't remember which, as I assumed it'd be fixed with the version upgrade ), and it did the same thing on my master backup computer, but when it froze, it'd have about 1,100,000K memory usage. It is not freezing on any other computers that are being backed up.
