I recently upgraded from 0.14.18+dfsg1-2+b1 (official debian stable package) to syncthing v1.0.0 on debian stretch installed via apt (as describe on https://apt.syncthing.net/) on my laptop and on my homeserver.
I share a documents folder containing between those two devices. Recently I added about 100.000 files and 30.000 folder (15GiB) with a single
mv call. The folder totals 101.000 files and 31.000 folders (25GiB).
The homeserver is behind NAT. The router forwards port 22000 to the homeserver. Up until now the setup worked like a charm for half a year.
Now syncing that folder is stalled at 65% for said folder. No data is transmitted, but both devices report each other as online. Transmission statistics are listed as < 1KB (818B UP, 611B Down)
Logs look clean to me. TCPDump shows traffic on port 22000 after syncthing starts. Then nothing is transmitted anymore. Right now I don’t know what else to do solve the problem.
Thanks in advance, Till
