Hi, I'm running Sync 1.0.134 on Debian Linux packaged by tuxpoldo. Any time a download reaches 2.5 MB btsync crashes. Restarting will continue the download until the next 2.5 MB is reached and it crashes again. Uploading works fine, and the crashing is reproduceable when syncing locally or remotely. If all files are smaller than 2.5 MB there is no problem, only for larger files does Sync crash. While watching sync.log I noticed that when Sync starts I see the following two lines: [20130430 09:10:04] total physical memory -1 max disk cache 2097152 [20130430 09:10:04] Using IP address 192.168.21.2 For some reason, after these two lines are written sync.log is immediately overwritten again, so they don't appear in the log after the crash occurs. On another Debian machine the physical memory is a number that makes more sense. I suspect that Syncs inability to determine the memory available is the cause of the problem...but who knows. I have started a request, but haven't received much feedback: https://syncapp.zendesk.com/requests/662 Hopefully someone has some suggestions. Thanks.
