After upping to v1.3.67 on Mac and Linux, most of my folders have never stopped syncing. It's almost like it's re-scanning the file structures, similar to if one was to re-add a sync folder that already resides on disk. No real data is being passed around, but it's been going for 2 days now. I thought something got tweaked out of line, so figured I'd delete each sync folder on the RO "clients" and re-add them (Linux webUI), and leave Mac "master" alone. The issue now is that after adding the secret, entering the disk path and hitting Add in the webUI, btsync shuts down. K'boom. So I can either sync forever, or not at all. During the never-ending sync, I'm seeing the following in the log, repeatedly: [20140326 16:37:49.171] Error downloading file <path> [20140326 16:37:49.394] <IP:port>: did not pick any blocks. blocking peer temporarily [20140326 16:37:49.500] TorrentFile: failed to copy stream suffix <path> [20140326 16:37:49.500] TorrentFile: failed to delete stream suffix file <path> [20140326 16:37:50.018] Error: <path> - PostDownload: hostname not found There's no log output for the crash, the log just ends. Help a noob? Interestingly, I just found that btsync won't stay running for more than a few seconds anymore. The "crash when I click Add" was just a wicked timing coincidence. Think I'm going to blow away btsync and start from scratch on one machine. If that works, I'll do the other one. But I'll hang for a bit, see if anyone has some tasty nuggets of wisdom ...
