I was testing syncthing how it will function in a larger client environment and I had a finding. I tested syncthing with 48 clients and 50 folders with different size (total of 20 GB). At first the synchronization went fine. But after a hour or so I noticed 5 clients stopped the synchronization.
I checked the following:
- The syncthing process is still running
- The rest API is still available.
- Calling GET /rest/system/config works fine
- Calling GET /rest/stats/folder does not work. It results in a timeout. Other calls involving the database, like statistics, also don’t work.
After restarting syncthing, or killing the process and restarting, the synchronization continues and completed successfully.
We are using syncthing version: 0.13.2.
I did not notice anything in the syncthing logfiles, with debug level ‘events’ (POST rest/system/debug?enable=events). I also checked the windows eventlog. There is nothing there related to syncthing.
Can you help me to investigate this issues. How can I approach this to generate enough information to solve this issues? Or is this a known issue/limitation of syncthing?
