(qemu-kvm 0.12.3)? Well, its funny how these things turn out. On Saturday, my better half insisted that I replace a mains socket. It wasn't on the same ring main as the server so I just switched off the relevant circuit breaker and got on with it. Unfortunately, whilst I was doing the work the main RCD tripped, probably because I let the Neutral and Earth touch which can cause that to happen sometimes. Anyway, by the time I realised there was a problem the old batteries in my UPS had given up and my uptime was over with a grand total of 382 days, 12:07:24! If this had happened a few weeks ago I would probably have thrown myself from the roof! In my previous house, I installed a special circuit for the server not protected by an RCD especially to avoid problems of this sort. Adding one in my current house has now moved a long way up my "To Do" list! The server has started again, but a few things still aren't happy. As soon as I have them sorted I will step up to the latest kernel and let you know what difference it makes. Thanks, Richard
