Hello I am using v0.12.7 on a FreeBSD 10.2-RELEASE system, starting the Syncthing binary from a terminal. Everything works great until I try and close Syncthing. Regardless of whether I close Syncthing via the web GUI or killing the process at the command line, closing Syncthing causes a kernel panic. Any suggestions as to possible causes/solutions would be gratefully received. Many thanks
