Once in a while, and only on one server (2012R2) Syncthing loses connection and starts logging continuously until all available diskspace is consumed and Syncthing goes into stopped-mode. The log when it starts is like this: [VISHJ] 18:47:05 INFO: Connection to JDB3PLR-HNWZ7H4-2ZDRVYR-HUKZ32W-LMXMAZG-3BBBOXH-GFIIS5K-DM3XDQL at 192.168.0.55:62260-212.47.253.154:22067/relay-server/TLS1.3-TLS_CHACHA20_POLY1305_SHA256 closed: replacing connection [VISHJ] 18:47:05 INFO: Device JDB3PLR-HNWZ7H4-2ZDRVYR-HUKZ32W-LMXMAZG-3BBBOXH-GFIIS5K-DM3XDQL client is “syncthing v1.3.1” named “Management” at 192.168.0.55:62638-80.56.17.214:22000/tcp-client/TLS1.3-TLS_CHACHA20_POLY1305_SHA256 [VISHJ] 02:39:53 INFO: Connection to JDB3PLR-HNWZ7H4-2ZDRVYR-HUKZ32W-LMXMAZG-3BBBOXH-GFIIS5K-DM3XDQL at 192.168.0.55:62638-80.56.17.214:22000/tcp-client/TLS1.3-TLS_CHACHA20_POLY1305_SHA256 closed: reading length: read tcp 192.168.0.55:62638->80.56.17.214:22000: wsarecv: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Then, it keeps repeating the last message over and over fillling up the entire disk. This is Windows 2012R2 Syncthing v1.3.1. I can’t find a setting to at least disable logging. Simply shutting down Syncthing and starting it solves it because it starts a new logfile. Annoying thing is however ofcourse that Syncthing stops without you knowing, so that node is then stopped/offline for as long as the disk holds out…
