Periodic transfer bursts, then no traffic.

Anyone seen a problem like this before where Syncthing is sporadically sending data? Connection is solid. One side is Windows version 1.30. The other side is a linux box running docker with host networking. Both are otherwise idle systems with very little going on. This is Wifi but it happens wired as well. I tried 2 wired adapters, a 1GBit adapter, and a 5GBit adapter (which I get 4.5GBit iperf3 to the linux machine on a 10GBit network.)

No indications in the logs something is wrong: No network disconnects. Syncthing shows 1+2 connections continuously. (TCP LAN). I tried 1+8 connections and also same thing. Same period. Same rough transfer rate.

Anyone seen anything like this?

Files transferring are a few thousand 50MB files. So it’s not a small file problem.

Any pointers where to look?

Is the linux side sending or receiving the files?

[mraneri (Mike)]

Sending.

Windows side is receiving.

if I copy the files manually via samba the connection is maximized and continuous.

If the filesystem on the linux side is case sensitive, does enabling caseSensitiveFS — Syncthing documentation help? You can do this by going to Actions → Advanced → Folders, and then expanding the folder having the issue, then enabling “Case Sensitive FS”.

I’ll try this on the Linux side although the documentation doesn’t recommend it.
