Have system syncing roughly 1.5 TB between two USB hard drives in separate locations. Files are located in 4 separate sync folders. Issue I'm having is that one or more of the synced folder will lock in "Out of Sync" state. I'm running V1.4.110 on a Win7 64 bit on one end and 32bit Vista on the other. Both ends are fully patched. Until today, I've always been able to clear that state by locating all 0 byte (non .!Sync) files on the receiving end of the "out of sync" folder pair. Today this failed. The only 0 byte files present had .!Sync extensions. I tried deleting these files, but they were recreated without restoring proper sync operation. (I.e., they were recreated but state remained "out of sync" and the Peers column showed 1 of 1 Peer like it should.) Today I did clear the out of sync state by stopping Sync on both ends (both peers simultaneously) then restarting BTSync on both machines. (Initially I stopped only one end but the fault remained after restarting that process.) Two notes: 1) I have never had this problem in the first folder (which is orders of magnitude larger than the others both in file count and total bytes and synchronizes many more files than all others together), only on the three secondary folders (most commonly on the second largest folder of the four which is the next busiest). 2) I attempted to collect logs today, but found that they restarted with BTSync and all information from the previous "out of sync" state was already lost. I still have thousands of files in the largest folder resyncing, so the logs use up the appearent 10 MB default size limit very quickly (in 2 to 3 minutes!). Anything I can do to increase this log file size and catch this in the act next time?
