This seems like a problem with the onboard wifi module in Rpi3. Restarting does not help.
Trying out two possible things for now:
Updating OSMC to latest version
Disabling power management for wifi
sudo iwconfig wlan0 power off
It seems to happen when transmission is heavily downloading.
Initially it seemed a problem of memory or CPU. But according to multiple issues reported:
https://discourse.osmc.tv/t/pi-3-wifi-unstable/14171/6 https://github.com/raspberrypi/linux/issues/1342
And the kernel messages:
