Yes, I seem to be able to ZZZ after boot (tried three times). So I guess it's fragmentation, but I must admit I thought I had bucket-loads (60%) of spare RAM, and wasn't getting close to using it all! Next time it fails, I guess it's worth me killing off a couple of big processes (e.g. browsers) to see if that helps matters along? Laurie
