Hello Sebastien, The problem did start after applying some upgrades, see log below.
It appears to be caused by receiving SMB requests from the Internet. This was happening due to a misconfigured router. Correcting the router configuration has stopped the problem happening. This also explains why I was only seeing he problem on two machines. ------start upgrade log------ Log started: 2019-05-02 16:19:12 (Reading database ...
